I was wondering if anyone out there has any suggestions on how to improve FCP performance. It seems right now the most i'm able to get is around 10-20 mb/s over a 4g pipe. To me that just seems ridiculous.
I did not get to set up these aggr, they were already provisioned this way when I came in.

Performance
Under load, CPU utilization is around 40%, ops/s stay between 450 and 750, I/O writes around 80mb/s and reads from 30-35 mb/s.
sysstat output shows FCP in and out never going over 10mb/s.
I've searched and searched and I can't find anything regarding normal FCP transfer speeds and what other people are averaging to compare what i'm seeing with to even know if what i'm seeing is normal or not. But 10mb/s over a 4G pipe can't be right in my eyes. Any input would be appreciated!
