I got a freenas Setup with the following hw:
16GB Ram
CPU: Intel G3258
4x2TB Ironwolf
3x1TP old HDDs
10Gbit NIC
When I have a raidz1-pool with the 4 Ironswolfs, my average writespeed on big files (movies 11GB) copied from my Windows-PC from Ram-Disk via SMB is max. ~150-200MB/s.
gstat shows that the drives are max. 60-70% busy.
When i do a raidz1 with the 3 1TB old HDDs and do the same copy-test speeds are about the same. gstat shows 100% load on the disks.
CPU usage on all tests max 75% on avg. 60% so CPU is not bottlenecking.
When i do a Stripe pool with either of the drives i get full bandwidth. eg. 3x1TB drive stripe ~275MB/s.
It seems like i do have a bottleneck but i cant find it, it seems like it is the Software?
I am running 11.2 stable.
Maybe someone can help me here. Cant believe 4 Ironwolfs do have the same performace as 3 old 2,5" HDDs :(
cheers
