Then explain to me why it was at times slower while on tmpfs? Trust me, I ran this test many times and in different orders and it did NOT make much if any difference. I might add, the cache on the drive I was using is nowhere near large enough to cache the tarball for the package. Heck, the cache on my current system drive is only 8Mbs according to hdparm. That is not much since I tested using much larger packages. You can't cache files larger than the cache. Do I need to run a test, reboot, run the test again to show this is not making much if any difference? I mean, really? o_O Dale :-) :-) -- I am only responsible for what I said ...
