Hello all, What is normal sys CPU usage in %? I have DualCore Xeon with hyperthreading, so 4 logical CPUs as reported by kernel (2.6.24.3), but the "sys" usage is about 25% (or 97% on scale when max is 400%). It grows proportionally with normal (user and nice) cpu usage, but seems too high for me. Server is running etch with php+mysql. Or is it normal? How can I see what causes it? Here is graph from munin: http://92.240.244.190/cpu-week.png -- bYE, Marki
