Good,
Ben
That has solved it. Now getting around 27MB/s write on ext4 and 97MB/s
read with the experimental kernel. I'm happy with these speeds on this
hardware. It is still a little slower then with windows but I can live
with that.
May be able to get better by tuning read-ahead buffer and
vm.dirty_rat

Running bonnie++ locally. Have formatted / as ext3 and /home/ as ext4.
using raid5. Also to note that when booted with windows server 2003
using Everest disk benchmark it does an average of 34MB/s (peaking to
50MB/s).
Attached are bonnie++ output for the two kernel versions and ext3 and
ext4 (ext4

Let's see the output from bonnie++. Also
Package: linux-image
Version: 2.6.32-5-686
After dist-upgrade from Lenny to Squeeze write speed is halved. Shown
with bonnie++. Before upgrade write speed was 21MB/s, after upgrade
10MB/s.
