Have you tried this with something like the kernel on a 128MB machine, or over NFS? Or, indeed, if you just do echo 5 > /proc/sys/vm/dirty_background_ratio echo 2 > /proc/sys/vm/dirty_ratio or similar, to tell the kernel to not allow a lot of dirty files. No, I've not tried it either, but you may think that checking files out is fast just because you're actually just writing to memory, and the background writeout will do the real work. That isn't always true. Checking files out can be very expensive indeed. Linus
