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)

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?
