Alright, so I investigated this question a little bit more:
Test: 102,400,000 Megabytes to IDE disk, with Pentium 166 or something like
that.
So the timings with mmap:
Write: ~28 sec
Reading: ~20 sec
With read/write, the speed-up stronlgly depends on how many bytes you write to
the disk at

Look at version 3.9.17* of XFree86 for speedups

gonna implement an MIT-SHM X drawing thing. This seems to be the

Wow, if I was manipulating nearly 100 terabytes of data I would opt for some
sort of SCSI RAID setup instead of IDE... :-)

Hi,
Please excuse a "not necessarily linux" question, but who wants to share
opinions/experience on the virtues of mmap ing a file as opposed to opening it
? I'm about to start work on a project where the local custom is to mmap input
files and I'm not so sure that's a good idea (the files and
