OK, I re-ran the tests on the same box using CURRENT as of this
morning. There does not seem to be any large difference speed wise between
RELENG_5 and HEAD, at least as it relates to the 3ware driver. Both
RELENG_5 and HEAD are behind RELENG_4 and Linux 2.6.10 which are pretty
equal in the tests that I did.
I could not run the full NFS tests, and async nfs mounts are broken in
RELENG_5 and HEAD.
F=RELENG_5
L=Linux 2.6.10
