Great! Frederic, since you just setup your system to do the jitter tests,
could you pl run them again (with the new code from CVS) and see what
difference it made (my own system is busy running the mird db power fail
tests).
Also enable profiling and see what else is on the "CPU hog" list.
The LTT (Linux Trace Toolkit) seems to be an excellent tool to get more
fine grained performance stats out of the system and
a new version was just released for 2.4.5 (though it may provide us with
more info that we need/can handle :)
