I have a Dell R510 with (Dual CPU / 6 Core) and 130GB of ram. My pool consists of three 12 disk raidz3 plus a mirrored SSD ZIL and a four disk SSD L2ARC. It's also on a fully 10 gig network (and reflects that in config). HBA is a beastly lsi 9300-16e.
Nothing I can do is making this thing break 50MB/s whereas my home budget raidz1 does 100MB/s and in comparison my windows boxes push 300MB/s (REFS raid60s). I'm just using a windows 2012 ISO file for every test.
I tried many different configurations (raidz1/raidz2/raidz3,mirror) even a single disk!.. always maxes at 50MB/s (with a flat transfer graph) Smelled like a protocol issue so I mounted NFS which was actually slower.. FTP same thing. Now if I transfer from multiple sources I'll get 40-50MB/s from each source.
I ran a local IOzone test and I was getting 250MB/s+ writes and 600MB/s+ reads (more what I expected)
Can anyone help me pinpoint the bottleneck? everything else has been flawless aside from this.
