Not much help, but I know there are some tuning parameters you can apply
to certain ext3 partitions to help with large I/O operations. I usually
just make those partitions ext2.
I almost always make /var ext2 especially on mail server or proxy
500Mb is so small these days, that I'm surprised it is causing you any
problems. Are the drives involved IDE?
