We are debugging a strange issue with abnormal CPU spikes occurring
in a test application.
CPU spikes are perfectly normal. If you start some calculation, the
CPU runs 100%, until done. If you do a short calculation, you get a
spike. Anything else would be a waste of time without a benefit.
The question you're after is probably, how are other tasks/apps/
threads affected by your app. This is where scheduling policies jump
into the picture.
On 10.4.3, the average CPU use on a dual G5 is now 0.6 %, but there
is no more CPU spike ....
The spikes are probably too short to be seen by you/your tool.
