[tracecompass-dev] Performance of CPU usage analyses with many threads involved

Hello,

Evaluating the CPU usage analyses and view I used sample/test data from here:

https://github.com/tracecompass/tracecompass-test-traces/tree/master/ctf/src/main/resources/many-threads

â and from here (see file attachment in the report):

https://bugs.eclipse.org/bugs/show_bug.cgi?id=460261

Trying to update the CPU usage graph with all threads selected the analyses took a very long time (>30 min) until Trace Compass (v4.2) was eventually rendered unresponsive.

It seems that in the bug report referred to above this problem (or at least parts of it) were addressed. However, I am not sure what performance and results are to be expected for this test traces. Is the CPU usage supposed to work and produce results with this trace data in TC version 4.2?

Regards,
Rudolf
