I have used xfs pretty extensively, it seemed to be somewhat faster than ext3.
The only trouble we had related to some machines running the PAE 32 bit kernels, where we the filesystems lockup. That is an obscure use case however. Running JBOD with your dfs.data.dir listing a directory on each device speeds things up, as does keeping other users off of the disks/machine.
