Have a look at these pages:

I'm comparing the default 5.1 64bit kernel with the patched one posted in the
bug report (kernel-2.6.18-53.1.21.el5.bz321111.x86_64) and I don't quite see
any significant difference in write performance for this command:
That's the wrong patched kernel. You'd need to be using one of the
kernels in <http://people.redhat.com/thenzl/kernel/> --
kernel-2.6.18-93.el5.bz444759.x86_64.rpm.
I'd be interested in a way of telling from within the OS whether or not
MWI is enabled...
