Hi,
I'm testing Solaris 11.3 ZFS with a single intel SSD 3500 600GB drive, it's being served to the client via SRP with infiniband 20G.
I"m getting around 1600MB/s read but only 300MB write, I've tried with cache, and or zil on other ssd's but never goes over 300GB write,
I installed ubuntu 15 desktop just to test the ssd drive speed, on the intel 3500 600GB I was getting 450MB read and write so it looks like ZFS is much slower on write ?
Hardware details below:
Supermicro SuperStorage Server 2027R-AR24NV , 64GB ram, 40g connectx2 infiniband car, dual E5 CPU's and 3x LSI 3008 SAS3 controller in IT mode
intel 3500 600GB drive,
OS installed on 120GB intel 3500 drive
