yea, I tried dedup, it worked badly. I didn't have enough ram (only 4GB of ram on my 5x750 raidz2 array) and it caused hard drive thrashing and terrible performance. I tried a pretty huge CPU upgrade (2ghz athlon64 x2 to 3ghz athlon II x4) and no difference in speed. I ended up disabling it.
I will just stick with solaris until FreeBSD stable release with version higher then mine is released.
