Have you considered async IO?
IF the data you load off of disk needs to be messed with after loading
(like, uncompressing), then async can help a lot.
To do it, get an example program (dospackets.c by somebody, on fish
disks somplace).

Basically it goes like this.
fh=Open("filename",x);
asendpacket(firstpacket)
wait()
do {
	asendpacket(nextpacket)
	processpreviouspacket();
	wait(for packet);
} while (!eof);
