[Clc-crux64] Performance gain?

Hi. I've installed Crux64 but theres some programs that i cant use (GtkRadiant for example) I'm thinking of installing avanilla Crux instead. Has anyone done some kind of benchmark compairing Crux64 with a vanilla Crux on the same machine? Is the loss in performance that big? Jan Pålsson aka zlotnik in #crux@freenode
