I run both the front end and back end on my desktop. The only time I notice it is when mythfilldatabase runs. The database
thrashes the disk and causes long pauses (10s of seconds) in other applications. This is not quite as flagrant as it once was,
but there is still the occasional hesitation when mythfilldatabase is running.

I also have the system set up so that it will shut itself down if I'm not logged in and the backend is idle, and will wake
itself when myth has something to do. This works better than any windows setup I've used.

This is an i7 920 system with 6 GB of ram, and a single 1.5 TB drive.
