Interestingly, as a project for work I've been benchmarking different
kernels against our configuration, using iozone.  The latest
redhat/centos 5.3 kernel against stock 2.6.27.8 (as close to the
centos config as is feasible.)

I have some pretty graphs, but the long and short of it is, while the
read times are comparable, the write times for the stock kernel.org
kernel are over twice as fast.  I mean it's pretty much blowing the
RHEL/CentOS kernel out of the water.
