Hello Benoit,

We have already investigated several performance/stability cases after ReSharper

5 release, and most of the time they were other extensions or Visual Studio

itself. I mean, before switching off things, it would be better to know the

real reason of the slowness. Is it possible you can download dotTrace 4 performance

profiler, capture a minute of slowness in a snapshot and upload it for us

for investigation? Thanks in advance.

Sincerely,

This is very weird - there's no ReSharper in the snapshot - it's all VS editor. What have you been doing while capturing the snapshot?

I am having exactly the same issue. Suspending resharper (disabling so it's not running) completely alleviates the symptoms. Scrolling the screen is laggy and typing is laggy at times. I touch type and it is disconcerting enough that I can't focus on what I am typing when it happens.

I have disabled the code analysis aspect and that seems to help. I am quite addicted to the navigation shortcuts so I don't want to disable resharper entirely, not to mention the fact that I have purchased a 5.0 license.

I would be happy to provide a profile if a link to instructions can be posted. Thank you for any help you can give.

Thank you!

Have you tried turning off the Navigation bar in Visual Studio?  I don't

know if that helps in 5.x on 2010 but it helped speed things up when 4.x

first came out on 2008...

I have uploaded two snap shots with settings to the public ftp upload listed in an above post. I hope this helps and the issue can be resolved or a workaround can be provided because I miss my inline code analysis.

JRoberts_scrolling_2010-04-23.dtp

JRoberts_typing_2010-04-23.dtp

Both of these snapshots were taken with R# code analysis on and 2010 reset with default settings.

Also, has any progress been made on the this issue?

Correct. Suspending resharper completely or suspending only code analysis restores performance to normal.

I do not believe that I have had that option turned on at all.

The behaviour is exibited with the following setup for code analysis options. X denotes a check mark.

x Enable Code analysis

  _ Color Identifiers

  _ Analyze Errors in whole solution

  x Show Analysis options in bulb menu

  x Show the "Import Namespaces" action using popup

Assume value can be null

  x When entity is explicitly marked with CanBeNull attribute

  _ when entity doesn't have explicit NotNull attribute

I am having what appears to be the same issue.  How can you suspend Resharper with uninstalling?

Yeah - there's definitely a problem here.  With R# running, over time, the perform degrades to the point where literally the mouse wheel won't scroll and typing lags a second per keystroke.  Suspending R# and the IDE immediately quick (quicker than VS2008 to me).  But even right after a refresh instance of VS2010, R# running is noticeable.  Naked VS2010 is faster than naked VS2008.  VS2008+R# is significantly faster than VS2010+R#.  VS2010+R# is barely usable (especially over time).

I've checked the snapshots you've sent.

We have found the problem which causes stucks in typing, and we'll try to fix it in bugfix update.

Thank you.

We will open EAP for ReSharper 5.1 in June

The slowdowns in .aspx files are fixed in 5.1 EAP which is available at http://confluence.jetbrains.net/display/ReSharper/ReSharper+5.1+Nightly+Builds

Same here. Unbelievably painful. 4GB of RAM and an SSD. And doesn't seem to be CPU either like Alex mentions. Scrolling, typing, doing anything... really slow with Resharper turned on.

I have just tried downloading the latest dotTrace beta, but I'm told my trial has expired. I downloaded this previously in the R# pre-releases to help with a few performance issues then too?

With R# 5.0 enabled, opening an XML file of 37mb cripples VS 2010. R# must be suspended before I am able to gain control of the IDE again. This was not the case with R# 4.5 on VS2008.

Is there a YouTrack issue on this?

Jeremy Roberts

Same problems here. Even with the Nightly Build from June 5. the Texteditor performance is nearly unbearable. Scrolling with the cursors (up or down) and even with the mousewheel is always delayed at least .5 seconds. Sometimes even more. Suspending Resharper removes the problem completely. Using a Solution with 20 Projects and a few thousand files. Solution wide analysis is off at the moment. I hope this will be fixed soon!! Working without resharper is really hard

We do not see these performance issues at our side

Please could you install dotTrace profiler and make a snapshot with this slowdown, and then send it to us for analysis?

Thank you in advance.

Hmmm...

I've checked that snapshot from he support. This problem is known - Garbage Collection during Avalon painting.... We are still investigating how we can handle this issue

I think it would be hard to estimate a fix version since they are still "investigating how to handle the issue".

To estimate a "fix in version" you generally must know how to handle the issue, or at least know the different options available for handling it to estimate work/impact.

just my 2 cents..
(I'm also longing for a perf. improvment fix, my cpu spikes all the time with vstudio2008/RS 5.1 EAP, but also did it with 4.5 so dunno if it's the same problem))

Hello Michael,

Could you please upload a couple of snapshots as well, so that we could confirm

Hello David,

There are several performance problems in ReSharper 5.0. Some of them have

been fixed and you can grab the latest nightly build with fixes at http://www.jetbrains.net/confluence/display/ReSharper/ReSharper5.1Nightly+Builds.

We're also aware of some of the others, but (as Eugene has pointed out) we

don't know how to fix them yet. There are also problems caused by Visual

Studio 2010 itself in combination with ReSharper and possibly there are some

issues we're not aware of yet.

So, in order to properly answer your questions we should first find out for

sure what kind of problem you're experiencing (since there're multiple kinds

of them). Please capture a couple of snapshots (the instructions have been

posted numerous times in this threads) and upload them to the corresponding

ftp server. After doing so, I'll be able to tell for sure if this problem

is known and if/when it will be fixed. Thank you!

I am also suffering terrible performance on a high spec machine with

the latest nightly build. Why is there no word on JB for this? Do they

acknowledge the problem? Is it effecting everyone? What are the plans

to fix it? We love resharper but we are seriously consider moving away

if performance isn't addressed soon

Andrey,

I was having the exact same problems: slow editing of ASP.NET files, slow navigation through C# source files, half second delays between keystrokes...

I just installed 5.1.1707.19. I haven't had a chance to do a lot of work with it yet, but I can tell already that these problems are all VASTLY improved.

ditto - no change in (poor) performance for me either.

FWIW: In my case it seems like the lack of available RAM is the critical issue (and/or the commit charge to the paging file).

I'm running 64bit XP dual core processor with 4GB RAM, using Visual Studio 2008.

After boot I generally have many apps loaded (indexing service, antivirus, IExplore, MS Outlook etc.).

If I work with Resharper enabled during this time it "crawls", making the work in it almost unbearable (simple things like renaming, goto definition, open unit test results etc. takes longer and longer.)

Suspending resharper makes things go fast again it seems (if comparing e.g. go to definitiion).

So I started to shut down every running non-critical app and used Process Explorer to monitor the Commit charge to pagefile and available RAM.

When almost all apps were closed, commit charge was about ~1.3GB and working with vstudio/Resharper went very fast.

I started some applications and I'm now up in commit charge 2.4GB (with 1.5GB availble RAM) and the response is still very quick.

So it seems either that a large commit charge to the paging file, and/or small % left of the total RAM is the critical issue in my case.

my 2 cents

I also experienced this problem in Resharper 5.1.

Now I have found out, that the StyleCop Plugin 5.1 causes this problem. If I disable this plugin, typing speed returns to normal.

I already reported this at the StyleCop issue tracker.

Best Regards,

Gerhard

Hello Andreas,

We've fixed some performance problems since ReSharper 5.1 release, so first

of all please install the latest build from http://www.jetbrains.net/confluence/display/ReSharper/ReSharper5.1.1Bugfix+Builds.

Let me know if that build works better for you. As to the memory usage, could

you please clarify if 270Mb is the managed memory usage reported by ReSharper

or if it's the memory footprint of devenv.exe process?

Me too am having serious problems with performance with R# 5.1 under

VS2010, and as already mentioned, things return to normal when

suspending R#. I already disabled the StyleCop plugin which did

improve performance but not sufficiently. I do use R# together with VA

and the codemap extension. Disabling VA doesnt change anything,

neither does codemap. So the problem is pretty reliably R#.

 

When will the performance problems of R# be fixed? Reducing R# memory

usage would also not be a bad thing. Seriously, 270 mb memory for a

solution with less than 3500 lines of C# code seems "slightly

exaggerated". The solution has less than 2 mb on disk

While there were numerous performance problems in 5.0, I can say 5.1 is muuuuuuch better.  I always want better performance, but what user doesn't (especially MY users:)?

VS2010 is still a huge pig, but at least for me, I don't feel like R# is the culprit anymore.  I'm running:

Just downloaded and installed latest build 5.1.1751.8 

Still unfortunately having the same issues - mainly slow / jerky at scrolling.  Got so bad had to disable resharper again and reluctantly do without it.

Looking forward to improvements in this area.

I'm following this thread from the sideline for several months now. We are using VS2008 and I would like to switch to VS2010 (we got the whole MSDN-chiladas), but one things is keeping me: this thread. At first, I thought JetBrains would quickly cook up a performance fix, so I decided to buy R#5 anyway. But now I have to choose: either stick with VS2008 + R#5 or upgrade to VS2010 and loose R#5. Either way, it's a loss of investment if the issues don't get solved quickly.

I know I could just go and try whether my system would suffer any of the issues in this thread, but I don't feel like reverting if it does. It's a shame JetBrains can't get this right and to my feeling, they start to really lose on it.

Woops - just noticed there's been a post on another formerly dormant thread here that is worth following:

http://devnet.jetbrains.net/message/5273251

Hello,

I know of two VS10-specific perf problems in R#, and both were fixed in 5.1.1.

The other perf issues should be more or less of the same degree on VS9 &

VS10. In fact, VS10 could even be a little better due to CLR4.

With R#, if you're switching between VS9&10, environment background color

is but the only noticeable change

Hello Andrey,

I dont see a problem in any specific action, but any and all editing becomes slow. Even moving the cursor comes to a crawl and I see CPU usage up to 100% while I move around, not to talk about typing code. It does however not effect the IDE itself, so any operation outside the code editor windows is normal. The problem is localized to keypresses in the the editor window(s). And it doesnt happen at once or immediately, usually it takes somewhere between 10 and 30 minutes of active editing.

My typical solutions consist of 2-20 C# projects and possibly some ASP sites and/or webservices. Class count goes from 50 to thousands, What I have noticed to be a serious problem for the R# analyzer are obfuscated assembly references. There are a bunch of exception reports on your system dealing with this. Might be that this is a trigger for the problems.

Number of open files in the editor is usually rather low, seldom more than fit visually on the tab bar (less than 10 commonly).

My hardware is either a VM with 2GB memory, hardware virtualization enabled with one monitor, or the real machine with 4 gb, 4 processors, dual monitor. The same problem happens on both configurations.

When I have time I will do some performance snapshots and send them to you. So far I am already spending much more time on solving R# issues than I'd like.

Hello Andreas,

I for one do not use R#'s Intellisense improvements at all because I prefer VisualAssist's, so R# is set to use VS's intellisense.

Your solution is not it, for me. Unfortunately.

Good tip, I've tried that out and it has made some noticeable difference for me. Although these were some of the features I use R# for, it is better than nothing at the moment.

I've noticed a significant difference in Silverlight projects vs. .NET projects, and to that end... any projects with XAML in them (Silverlight or WPF) are significantly slower - and Silverlight is more so than WPF.  When I say slower, I mean all-things-text-editor related (typing, scolling, intellisense)

After R# 5.1's release, I've been pretty happy... until this week when a huge .cs file was added to one of our projects that was the output of several XSD.exe runs.  This file contains a couple hundred POCO classes.  Even after wrapping all the generated code in a region and added that region text to the Generated Code list in R#'s options, the entire solution went to a crawl.  Now I hate VS+R# again

I'm only on this project for a couple of more days, so I don't care to investigate much further, but... some observations for you all

Hi Kirill,

You should be able to reproduce this problem (well the problem i was having) by doing the following:

1. Download the .NET version of quick fix from here: http://prdownloads.sourceforge.net/quickfix/quickfix-bin-vs10-1.13.3.zip

2. Extract the zip file to you PC

3. Create new VS2010 project

4. Add a reference to the lib\quickfix_net.dll and lib\quickfix_net_messages.dll

5. You should see slow down. If not then try using some of the Message class within the quickfix_net_messages assembly. When i do this VS2010 is basically unusage with R# installed.

Cheers,

Dom

Hello Michiel,

We're sorry for the problems you're experiencing with ReSharper. Could you

please take a couple of performance snapshots and upload them to our ftp

server? This would really help us to find out what goes wrong with ReSharper

on your machine/on your solution, so that we could fix it. I'm afraid we

won't be able to address this problem without a snapshot or a sample solution

with repro steps. Thank you!

I just installed the 5.1 trial and the performance has not improved at

all compared to 5.0. Right now, as I'm typing, Visual Studio is trying

to open a 25 line .cs file in Visual Studio, it's taking about 5

minutes! Of course, everything goes back to normal after suspending

ReSharper.

 

Will this issue ever be fixed? It's the most discussed on the

ReSharper community...

 

Thanks!

Hello Michiel,

I've played with the original Kentico web site for some time (performing

various actions such as navigating, finding usages, refactoring, typing,

scrolling) on an underpowered virtual machine and didn's face any performance

problems. Could you please describe your hardware configuration in detail?

It would be great if you could attach a small screencast demonstrating the

actions you're performing in Visual Studio with Kentico CMS Web Site, so

that we could repeat them on our side. Thank you!

I am working on a solution that includes a commercial CMS.

Unfortunately it's distributed as a Web Site project containing 12.500

files, among which 2000 .cs files, 1000 .aspx files (ASP.NET pages),

750 .ascx files (ASP.NET user controls) and 68 assemblies.

 

You can download the http://www.kentico.com and install it to see how

Visual Studio performance is impacted by this type of project when

ReSharper is installed (basically unusable on my machine).

 

Looking forward to your response, and any tips you have to get

ReSharper to work in this scenario.

 

Thanks!

http://devnet.jetbrains.net/message/5274378#5274378  I've been having a pretty good run after switching Resharper back on.  It slowed to a crawl once, but I've had that with VS.  That was after quite a few hours of work interspersed with a couple of hibernations.  Right now I'm very happy.  Thank you Jetbrains for your efforts to rectify the problems.
