Hi,

There is no defined  path for checkig this kind of situvation.
But will try ..

first you should fine whther its b'cos of CPU ,IO or network.

use /usr/ucb/ps -aux and check first few entries.

Then you have to figure out whther its b'cos of  a system process or a user
process.
vmstat  2 10
Check first 5 and last 6 columns.( also sr field)

you can also use ( When the system goes slow)
iostat -nx 2
netstat -a
sar 2 10
mpstat 2 10

if you can send some sample out puts I may able to check whats wrong.
