Doesn't the agressive use of cache and buffers in the 2.4.x kernel 
really speed things up, when you have plenty of ram?
Since I upgrade my computers regularly, it's harder for me to tell, but 
I am convinced that the 2.4 kernels in Redhat 7.1+ is faster than in the 
2.2 kernel in Redhat 6.2.

Does anyone else remember the difference in performance between a 2.2 
and 2.4 kernel?
