Hello, I'm using a Sun Fire X4500 "Thumper" and trying to get some sense of the best performance I can get from it with zfs.
I'm running without mirroring or raid, and have checksumming turned off. I built the zfs with these commands: # zpool create mypool disk0 disk1 ... diskN # zfs set checksum=off mypool # zfs create mypool/testing When I run an application with 8 threads performing writes, I see this performance: 1 disk -- 42 MB/s 2 disks -- 81 MB/s 4 disks -- 147 MB/s 8 disks -- 261 MB/s 12 disks -- 347 MB/s 16 disks -- 433 MB/s 32 disks -- 687 MB/s 45 disks -- 621 MB/s I'm surprised it doesn't scale better than this, and I'm curious to know what the best configuration is for getting the maximum write performance from the Thumper. Thanks, -- Bill.
