Phoronix comparision of HAMMER, UFS, ZFS, EXT3, EXT4, Btrfs

[Miroslav Lachman]

Another filesystem benchmark from Phoronix. This time comparing HAMMER, 
UFS, ZFS, EXT3, EXT4 and Btrfs on DragonFly BSD, PC-BSD and Ubuntu.

I think it is almost useless test if systems were crippled to UP, 
because of bad SMP performance of DragonFly BSD.

citation: "...the SMP performance under our setup was actually much 
slower than with its UP kernel. As a result, we used the stock 
DragonFlyBSD UP kernel and when benchmarking PC-BSD and Ubuntu we 
disabled the SMP support there."
