(3) posix_fadvise on Linux is a bad idea... the good news is that it
is not needed there:-) How good or bad an idea it is on other system
is an open question...
I don't know what is the best way to verify that, if some body else has
access to such a m/c, please help to get that verified.
Why wouldn't we just leave it out then? Putting it in when the one
platform we've tried it on shows a regression makes no sense. We
shouldn't include it and then remove it if someone can prove it's bad;
we should only include it in the first place if we have good benchmarks
showing that it is good.
Does anyone have a big Windows box they can try this on?
Just a box with a disk would be enough, it does not need to be big!
As I wrote before, FreeBSD would be a good candidate because the
posix_fadvise seems much more reasonable than on Linux, and should be
profitable, so it would be a pity to remove it.
