Snapmirror NTAP is at 20% constantly

Hi Guys,

Any reason why CPU utilization on my snapmirror destination is always at 20%??? My production filer is much less than that. The Snapmirror only happens once per day. All other indicators seem idle. Here is a sample output:

CPU NFS CIFS HTTP Net kB/s Disk kB/s Tape kB/s Cache in out read write read write age 22% 0 0 0 1 1 65 59 0 0 4 20% 0 0 0 1 0 121 120 0 0 4 26% 0 0 0 1 1 336 59 0 0 3 22% 0 0 0 1 1 2017 472 0 0 3 23% 0 0 0 1 0 2461 413 0 0 3 22% 0 0 0 1 0 2334 182 0 0 3 24% 0 0 0 1 1 1307 206 0 0 3 20% 0 0 0 1 1 61 59 0 0 3 22% 0 0 0 1 0 123 118 0 0 3

Another question -- Is there a way I can monitor utilization/performance of NVRAM and Memory? What other perf commands can I use other than sysstat?

Thanks
