Going to try the async mount without softupdates on /usr ...where /var/qmail is a symbolic link to /usr...otherwise i run out of inodes from lack of space in /var. So I will go ahead with async and the todo patch from the previous email someone kindly sent about qmail....see how much performance I can get. I'll keep you informed.
