Yes, I think so.

The 348 box is runlevel 3 by default and is very snappy.

The 700 Mhz Celeron slowpoke is runlevel 5 by default, but I'm talking
console in the above, and it's the same slowness regardless.

On the other hand, the slow poke responds very snappy over console ssh.
It's only on its own consoles that it's bad. I can't test at the moment
because it is setup as my pristine FC4 box as we try to put the Speakup
Modified for FC4 together. So no speech there right now. I will try re
display response when someone sighted shows up here.
