Want to test the write speeds on your ZFS array?
An easy way to do this is:
time (mkfile 100g /tank/foo)
You will get an output looking something like this:
real 5m01.332s
user 0m0.335s
sys 0m37.958s
To calculate how many MBytes per second the write was, you can use the following formula:
number of MB (102400)/number of minutes (5)/60 = MB/s (in this case it would be 341.34 MB/s)

Take a look at filebench (it’s in /usr/benchmarks) for some interesting read & write tests for zfs.
Thanks Mark, will definitely have to give those a try!
