suppressing syncs on spools

[Bernhard Erdmann <be@xxxxxxxxxxx>]

Hi,

for a spool/scratch filesystem I'm only interested in speed. Disk I/O
should be as minimal as possible. Files will be deleted some 1/10 sec or
some secs later. It won't hurt if files are lost if the box crashes.
This filesystem can even be mkfs'd at system boot.

Just speed, like a ram disk, but I don't want to spend 1-2 GB to a ram disk.

Are there mount options or mkfs.xfs options which can help to reduce
disk I/O?

Regards
Bernie
