You need to use 'top -m io' to see what's going on with your I/O.

Also, note you're not running on recommended hardware, as a result you may find suck oddities like high interrupt utilization.

thank you. I know I am not using recommended hardware. However I have not had any issues for the 3 or 4 years that I been using Freenas. This issue is new and it only happens from time to time.

I learned that if only one client is attached to FreeNas, all is ok. As soon as a second client is attached the Interrupt cpu usage goes higher. I have attached screen shots of "top -mio" for normal and high cpu usage. Can anybody suggest why this is happening?

I am sorry I am back on FreeNAS-9.3-STABLE-201512121950. I had forgotten to change my signature.
