Actually Dave, being a little more constructive, have you had a chance
to try the new aio code in Samba HEAD on Solaris yet ? It actually might
make a difference on Solaris. On Linux aio performance makes things worse,
as they don't do it in the kernel - they create a pthread to handle the
aio calls - which really sucks :-).

I'm guessing Solaris does this (correctly) in the kernel and this
actually will improve speed on a loaded system (especially when re-exporting
a clustered filesystem) but it would be good to get some confirmation
before I move the changes back into the release branch.

Cheers,
