Not in the UP case.
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
