Hi Raj

what kind of slowness you found?

Check your disk
#sar -d 5 5

check CPU usage

#sar -u 5 5

check iostat

check memory usage

#swapinfo -tm

if you have glance plus

go there and investigate where is the problem.

Hi,
You can use "kmeminfo" script which will tell in details of per user basis cpu and memory usages.

Thanks & Regards

Hi,

Is there any monitoring tool.

If glance is Installed use #gpm command.
or #glance .

Also check sar -u 1 10

hi,

are you observing any particular symptons either at the application level or Operating system levels?

What type of application are your running?

Is the kernel properly tuned?

revert!
