Just to add to the fodder..
Have you looked at performance advisor? I use it from a high level on whats really busy.
Also, if you've reciently added spindles to an existing aggr, may need to run a re-allocate.
Maybe don't have enough spindles for the work loads. Little value add here, but maybe you need (if you don't already have it) a PAM card with the appropriate size.
Just thought I would throw that in.

Hello All,
We're troubleshooting some performance issues and trying to determine how deduplication might be might be muddying the waters on an already busy v3170 HA filer pair. There's also some likelihood that snapshots are involved.
Why do you need to run the de-dup process daily? In our environment, we set the schedule to auto & let the filer manage it based on the threshold and still see very good de-dupe ratio and good performance. e.g.: Filesystem used saved %saved /vol/vmstore1/ 446GB 301GB 40% /vol/vmstore2/ 607GB 281GB 32% /vol/vmstore3/ 693GB 245GB 26% /vol/vmstore4/ 494GB 197GB 29% /vol/vmswap/ 81GB 95GB 54% /vol/vmstore5/ 1378GB 461GB 25% /vol/vmstore6/ 70GB 57GB 45% /vol/vmstore7/ 4598MB 624MB 12% /vol/vmstore8/ 329GB 109GB 25% /vol/vmstore9/ 446GB 90GB 17%

Hope that helps
