I don't think you're being fair. I'm running IRIX 6.3 on an O2 R5000, and
if I go to run an application, like video editing, and it immediately
seizes everything my program requests. I've also watched a top showing
that it usually never gave up less than 6% though, which is reasonable

Regardless, I can hardly tell the difference and I believe you're just
bitter about an older version of IRIX.
