That's funny, the main reason I switched to FreeBSD was it performed better / faster - especially under load - heavier the better :) > Are there any performance tweaks to increase my system's operating speed? > I'm currently using the 4-CURRENT, async io and edited the kernel config > file for as much speed as possible. If your running -Current try switching to softupdates rather than async IO - The _only_ area I found Linux used to be quicker than FreeBSD was with filesystem throughput, which is apparntly because they run their filesystem as the equivalent of 'sync', I'd always been more than willing to pay the price of 'async' vs. 'sync' on the damage recovery front... -Current lets you use softupdates, which really are pretty much best of both worlds (fast, and safe). Other than that - do you have any quantitive figures for 'slower'?, e.g. "my program takes 40% longer to compile" or anything? > Please reply by email too. Have done :) ...
