My i386-core2duo with SMP kernel gives _wonderful_ responsiveness, even, with buildworld -j5, I absolutely don't feel any slowdown! But when I once accidantially installed a UP kernel,the machine was very "laggy", I want to say had short "freezes" I'm also wondering that inserting a CF card in my card reader stops all io for a second. HALd is probably the culprit, but why can the system be stopped by userland? Maybe unrelated to ULE though. Thanks
