If you've got plenty of RAM (my machine has 64GB) then a good sized tmpfs (32GB here) mounted at TMPDIR (the local.conf setting, not /tmp) in with rm_work means you literally have no I/O latency.  To persist files either copy them out or for example set DEPLOY_DIR to a real disk.

One thing you’ll find here is a lot of very knowledgable people who go out of their way to help as much as possible - got me going from a cold start very, very quickly :-)

A really good example of an excellent opensource project / community.
