Freenas Nice Parameters
I have a Xeon E5 2683v3 that is being maxed out during verification. I've looked around and tried "-n10" to avoid the issue without any luck. Can anyone recommend parameters that will only use ~50% of the cpu resources?
Re: Freenas Nice Parameters
You have a 14 core / 28 thread Xeon system?! And all those cores are used by SAB?
Anyway: "during verification"? Is that the par or the unrar process? If so, which one? Those programs have parameters to set the CPU load:

You must specify a Recovery file.
Concurrent processing utilises Intel Thread Building Blocks 4.3 Update 1,
-t<+<n>|0<n>|-<n>>: Threaded processing. The options are:
-t+ to checksum and create/repair concurrently - uses all available logical CPUs - good for hard disk files - [default]
-t0 to checksum serially but create/repair concurrently with all available logical CPUs - better for slow media such as CDs/DVDs
-t- to checksum/create/repair serially - uses a single logical CPU - good for testing this program
-t+n to checksum and create/repair concurrently - uses n logical CPUs (up to all of the available logical CPUs)
-t0n to checksum serially but create/repair concurrently - uses n logical CPUs if n > 0, or all available CPUs minus n if n < 0
-t-n to checksum and create/repair concurrently - uses available logical CPUs minus n, eg, -t-1 on a 6 CPU system will use up to 5 CPUs

Re: Freenas Nice Parameters
Sorry for just now getting back to you, it seems to only happen when a repair is needed and then it reaches the verification stage, just experienced it and I had a load of 28 so it certainly uses all of the resources it can.
Re: Freenas Nice Parameters
I would suggest to set the extra parameter to lower the number of threads used, as sander suggested before.
