There are a few ways you can check

 

sysstat - controller performance statistics (normally I specify interval = 1, for immediate result)

netstat - network performance statistics

protocol specific

NFS

CIFS

iSCSI

And also performance advisor ..generally I start from latency, network throughput, try to narrow down the possibilities and find out the bottleneck.
