ZFS benchmark

ZFS benchmark

I have a 64-bit box with a ZFS raidx2 array. It now has 4GB of RAM and I recently purchased another 4GB.
I thought I might do some benchmarks on it before and after I install the additional RAM. I will be using
the benchmarks/bonnie++ port.

The intial tests

In this section I will run two intial tests. One will write to a zfs dataset which has compression enabled,
and the other will be to a dataset which does not enable compresion. The latter will be first:

1 thought on “ZFS benchmark”

  1. After talking with pjd regarding benchmarks, the following ideas came out:

    * benchmarks/filebench
    * sysutils/fio
    * collect data from ‘sysctl kstat’
    * I might also run sysutils/zfs-stats
