Re: vmstat
faults
-------
in sys cs

What does the above mean and how critical it could be.
What are the other factors that need checking.

Re: vmstat
if you have glance, you can narrow down problem easily.

Solutionin -> Device interrupts
sy -> System calls
cs -> CPU content switch rate.
Here, you have high number of system calls, and very low device interrupts and CPU switching.
You cannot simply depends on vmstat output. You may have to look for some other utilities to find out, what raised so much system calls. Whether it is from user generated or something else. You can use sar or glance to find out that.
Second it depends on your system load. I think, it is reasonable value. I have seen many production environment, sy is always higher.
