Although this is unrelated to the current topic, we were running an old bandtest.dll version so maybe that's what was causing the lag. If you haven't tried recently (within the last week or so), try again. It /should/ be better.
Also, @shaitan, I knew this could be an issue and I offered WD (back when this topic was first posted) to pay for a separate server. WD did not feel it was necessary and that it could be hosted on one of MPF's servers at the moment.
