[BUGFIX] Apply thumbscrews to sqlserver

sqlserver is a special race that welcomes high memory servers as its
habitat. However, we are short on resources and need to offer a very
small amount of RAM for a living which already acts as server cruelty.

While we're on it, it gets a nice bed to put some data on the RAM disk
in the hope its job gets done at least quicker.
