Freenas not reading cores correctly/Performance questions

[Th3RadMan]

Appearently I just hit something I shouldn't have and now Freenas says across my 2 2670's I have 32 cores on the dashboard. When I open a vm it still limits me to 16 cores, as expected, but I look at system monitoring programs, things get a bit funky. If the cores per package is set to 8 and threads per core is 1, I get 8 cores, 8 threads, and 2cpus, for a total of 16 cores/threads . When I change the threads per core to 2, I get 8 cores, 16 threads, on 1 cpu. I am trying to figure out how to use the hyperthreading (if possible), or at least get everything balanced correctly. If you can't use hyperthreading, then the 2 cpus and 8cores/threads makes sense.

Loaders added:
hw.vmm.topology.cores_per_package=8
hw.vmm.topology.threads_per_core=1

I reset my bios and changed any recent Freenas settings back to their original state, but it still says 32 cores. Is there something that might have caused this issue?

As for performance, I believe this is closely related to the above topic. In my current config, dealing with the issues stated, I'm getting a bit above half the performance seen by a dual 2670 setup. It might be because it is a VM, but I hope not.

What is a VM? Are you running the FreeNAS instance inside a VM?

Freenas 11.2

Why are you running the Release Candidate instead of the latest stable release, which is 11.1-U6?
