Hello, I made some dd measurements this time I tried Ubuntu as reference with ext3 and zfs-fuse to judge on the OpenSolaris figures. Please note that I ensured that the zfs-cache is empty before trying to read. As you can see from the figures they are amazingly good. So ZFS is not the bottleneck. The Samba values of Ubuntu where a little bit better compared to FreeBSB but absolutely unstable.
So what I see is ZFS is performing well and Samba or CIFS is performing well also but the combination ZFS + Samba/CIFS really takes down the performance on my board. Any hints?
