The best way to get started is probably the performance cookbook. See here:

Performance issue are caused due to CPU/DISK/MEMORY/NETWORK Bottleneck

To identify where the bottleneck is
For CPU:

# sar -Mu 2 2

>> check %idle, This is the IDLE CPU time

For DISK:

# sar -d 2 2

See that avwait < avserv and is not high
Also the disk utlization should be normal(%busy)

For memory :
>> Check that you dont have any page-out(po) happening

# vmstat 2 2

## Check for the free memory on the server from top command

# top

Look in

Memory .. ... .. XXXX K Free

Look out for Free memory here,,This should be sufficient

Network:

Run script provided by HP like lanshow to check the network inbound/outbound traffic
