I'm using Zevo on a somewhat older Mac (2.6 GHz, dual-core, 4GB RAM).
I have a couple of USB drives, formatted ZFS.
When the drives are formatted with HFS+, I'm seeing reasonable drive performance for the specific device - 20 MB/s writes, 40 MB/s reads.
However, when formatted as ZFS, I'm seeing pretty horrifying speeds: less than .5 MB/s writes, for example, with a 150 MB file.
I'm running the current release of Zevo.
Does anybody have an idea what may be wrong?
