It *should* be faster now with new disks in place. Old SSD:
>read: IOPS=1835, BW=57.4MiB/s (60.1MB/s)(6883MiB/120012msec)
>write: IOPS=1836, BW=57.4MiB/s (60.2MB/s)(6886MiB/120012msec); 0 zone resets
New zfs pool on two SSDs:
>read: IOPS=8124, BW=254MiB/s (266MB/s)(29.8GiB/120003msec)
>write: IOPS=8135, BW=254MiB/s (267MB/s)(29.8GiB/120003msec); 0 zone resets
It also takes less space thanks to lz4, but it's not like running out of space is a concern for me anytime soon now.
