Why is FreeBSD so SLOW?

I have noticed in general that any *nix distribution gets slow if the network is configured badly. On a well configured system freebsd is much faster than linux and that itself is much faster than windows.

Sounds like a troll... but I have nothing better to do as of currently.

If blackbox is not playing nicely then something is def wack with ye's system. I've never had any probs with that WM.

Sounds like you have configured something badly. I've used slower system with crappier hardware and had no problems and it had no problems playing movies. It ran quite nicely.

Are you using a optimized kernel? Are the ports ye are using optimized? What about mem leaks?  Is some program eating a massive number of cycles?
