It only benefits performance if it's on a seperate *disk*, not just a seperate
partition. It may help stability to put it on a new partition on the same
disk/array, but not performance.
Also, if you're already on a RAID 1+0 array or a large RAID 5-7 array (5 disks
plus), moving WAL may not be a perceptible benefit at all.
What OS are you using?
