In Linux the FAT support is pretty slow because NO BODY wants to optimize it!
Linux is pretty fast in disk access because it uses ALL the memory as cache 
(like in Lose 95 but better implemented). Another thing (even when you didn't 
it) never try to compare a DJGPP program running on DOS v.s. the same program 
compiled on Linux if the program uses heavilly the disk, the Linux version is 
MUCH more faster for a lot of reasons (no real mode switch is the most 
important I guess).
