By the way, I've found a temporary workaround, in case anyone needs it: mount the filesystem through a loop device (-o loop), and BLKBSZSET the underlying uba partition to 4k; this brings speed back up to 400k/sec. (Unfortunately, -o loop is incompatible with umount -l, which I'm depending on, so it's time for some hackery ...) -- Glenn Maynard ------------------------------------------------------- This SF.Net email is sponsored by Oracle Space Sweepstakes Want to be the first software developer in space?
