Serge, in IDEA version 8, is all this still valid? i notice thread dumps already in my logs directory. is this mechanism for a total lockup of the IDE when there has been no automatic thread dump?

Thread dumps do not replace CPU snapshots. Dumps are for complete UI hangs, CPU snapshots are for performance problems.

And for 64-bit Linux, use -agentlib:yjpagent64 which is included in the EAP's if not release version.

It would be great to remove the information for ancient versions from the document in order to make it easier to read / follow.

I tried to add the yjagent64 but it does not want to show in the toolbar. Still I can see the two icons in the toolbar editor but I am not able to convince PyCharm 1.2.1 to display them.

Make sure to use YourKit 8 libraries.

IDEA 10 has both 32-bit and 64-bit libraries bundled, therefore this step is not required. -- This makes the entire paragraph skippable, from my knowledg PyCharm 1.2.1 is based on IDEA 10 codebase.

PyCharm distribution differs from IDEA, it doesn't bundle 64-bit executables and 64-bit profiler libraries.

What you say is strange, considering that Activity Monitor reports PyCharm as a 64bit process and that I was able to capture CPU usage data of around ~1mb (zipped).

What I said applies to Windows platform. On Mac/Linux architecture will depend on the used JDK and user preferences for the application.
