HP Proliant Microserver Gen 8 with CPU;
Intel(R) Celeron(R) CPU G1610T @ 2.30GHz
16 GB ECC
4 x 3TB Seagate NAS HDD, Raidz2
GBe network
I'm about to start over with my installation, I've misunderstood some essential stuff about permissions, users and groups and it just feels good to start over. Someone told me that changing "Permission type" from Unix to Windows on a dataset will mess up permissions, so I'll just start over.
But first I need to get back some data from the NAS. I noticed when I uploaded via FTP I got about 110mb/s, but downloading "only" gets me 80mb/sec. And when transferring via CIFS I get about 70mb/s.
So I tried arcstat while transferring back files now and see this
Is this something that could be fixed in tunables, or would I need to get more RAM or add an SSD as a L2ARC?
The CPU usage is at 10%.
Thank you!
