I am running 8.0 RELEASE and I am having some issues getting everything to run right.
For example, I have 4 2TB drives in a raidz1 zpool. The maximum write speed on average I can maintain is 4megs. I have used iostat to see what was going on....
Bursts everywhere. I will get a burst of 40megs then nothing for 3 to 5 seconds, then another burst...
I have tried tweaking things such as the kern.maxvnodes=250000/vfs.zfs.prefetch_disable=1/vfs.zfs.txg.timeout=5/vfs.zfs.txg.write_limit_override=256m
And it helped a little bit, but not much. Whats wrong?
