Why I think FC3 sucks!

[Gain Paolo Mureddu]

Hmm... There may yet still be a reason why you notice such a slowdown 
with FC3 when compared to FC1&2: SELinux... Yes, it increases system's 
security, but on some cases it may be too much an overhead to the system 
and indeed a system hog. In my case since I use custom built kernels 
(due some odd hardware that I would not be able to use otherwise) I have 
to shut down SELinux to successfully boot the kernel (other wise the 
audit will fail and boot will stop). Try that and see if your 
performance increases... I'm sure many on the list think otherwise 
regards this, but in my experience it has worked.... I went from 106 
processes (fresh boot into my session) to 83 when disabled this.
