There might be some problem with my server,
because every morning at 7, it's performance become bad with no DB extra deadlock.
But I just couldn't figure it out.
Please give me some advise, thanks a lot...
According to the CPU performace chart, Daily CPU loading Maximum: 42 %, Average:36%.
But I have a serious Report Delay for almost half hour.
Here is the "TOP", at the same time but the next day I collect.
How can I measure CPU loading (like performance monitor in Windows OS). I use Solaris but I would like to write portable code.
Besides, I have to write programm to load CPU with known percent. How can I use CPU in 30% for example.
Thanks for any ideas. (6 Replies)

What is the reason? ... (7 Replies)
