There's also a lot to be said for dumping to a dedicated local drive
with fsync turned off.  They're logs so you can chance losing them by
putting them on a cheap fast 7200 rpm SATA drive.  If your logs take
up more than a few megs a second then they are coming out really fast.
 Do you know what your log generation rate in bytes/second is?
