Hi Vivek,
As I mentioned in the private reply, you need to take two snapshots of
netstat output (over 10 sec interval for example) and calculate delta
between corresponding bytes/sent values (also for bytes received values) to
see whether the TCP traffic is anywhere near your network link bandwidth. If
it is you're experiencing network link bandwidth issue. If it isn't then
it's something else (like wrong TCP buffersize settings but it could also
indicate a bottleneck in your (V)LAN infrastructure)

Folks
Following are an AWR snippet & "netstat -f inet -p tcp" O/ps taken under
Peak Benchmark Load period of 5 minutes
Does the following indicate Network Bottleneck?
