My experience is that the kernel.org kernel performs very badly under heavy
disk IO when you have 4G of RAM. There are patches to fix this, I can't
remember which ones they are (and I couldn't find the patches on their own
when I looked).
I solved this before by using a SUSE kernel source tree, but a Red Hat kernel
source tree has the same patches.
