Here are new screenshots for Jaunty and Karmic. Each test ran for a good 25 minutes. I've also added a Karmic screenshot for 'top' showing (some of) the threads associated with the single Java process. In addition, I have copied my recent post (2010-03-10) to <email address hidden> :

--------
Can anyone tell me whether the Karmic kernel has implemented a different
way of what it considers a process (as opposed to threads)?

I have a situation where CPU load is zero on Karmic but considerably
higher in Jaunty and earlier.

The scenario is a single java process with many threads. The system has
4 cores and only one java process should logically produce a negligible
CPU load but why was this not the case with earlier kernels? Has
something changed in Karmic that would explain what I'm seeing?
