This will be just as slow on a 600M filesystem...
If there are a lot of files, it's going to take a rather
long time to remove them. (Just try this under Windows:)

On my 120mhz HP-UX system this same operation on the same set of files
with the same model disk drive only takes a few seconds; whereas with
my 200MHz PPro Linux system it takes five to ten times as long...

Is it possible to optimize this?

Fsck takes extremely long because it has to cross-reference
all the inode and directory data...

Yes, this is probably unavoidable...

Thanks,
Mark
