I'm finding that the hard disk is the massive bottleneck in achieving this.
I'm running Solaris and am looking at the possibility of having the queue on
tmpfs so it's in RAM. Of course, on reboot or crash the directory structure
would be gone.. how much of this directory structure does qmail expect to
find, and how much of it will it create on the fly? Any other suggestions?
I'm assuming that you'll mount the tmpfs as /var/qmail/queue. After
mounting, before running qmail-start, just run "make setup" from the
qmail source directory. That will give you a clean queue.
