Calculate vxfs millisecond delay

We have a Netbackup master server cluster, the catalog/DB is sitting on a vxfs volume. 

There is a case open currently with Veritas and they have found massive delays (40 seconds!) at backup peak time on the Sybase database and have recommended we do a "nbdb_unload -rebuild" and "nbdb_admin -reorganize".

Meanwhile, we are looking at the IO on the catalog/DB volume. The technote below says the response shouldn't be more than 20ms. How do I determine the current response time, is there a Storage Foundation tool that can provide this?

Our host is running RHEL6.6.
