I am running a FreeNAS 0.7 on my testserver (Sempron 2600+, 1.5 GB RAM, HDD Samsung 1x SP2514N 3x SP2014N).
The OS is running from the 250 GB HDD, the rest of this disk is used for 'permanent' data. The three 200 GB Disks are used in an zpool for tests (sometimes assembled as an raidz, sometimes only a stripe).
I've implemented some additional FreeBSD Tuning variables and I get nice preformance out of this box...

What tuning did you do to yours?
I've made changes to sysctl.conf and /boot/loader.conf per the FreeBSD ZFS guide, and I can push close to 70MB/s to / from my freenas ... but the transfers are very "spikey" ... 70MB/s for 5 seconds ... nothing for 5 seconds, another burst, etc.
I'd love to hear if you had this problem and overcame it :)
Hi charles,
this was some information I've described now in my new blog entry -> http://harryd71.blogspot.com/2008/10/tuning-freenas-zfs.html :-)
I don't have the experiences that you've described. I can see a throughput of around 50-60 MB/s.
Can you describe your configuration in more detail. If you wan't, you can contact me (harryd71@users.sourceforge.net)
Regards, harryd
