Same here...couldn't get it to load at all past the logo for awhile. But I *still* see no speed difference, $2K software or not. The 2 grand could be better spent somewhere else than on speedup software IMHO.
Maybe Johan is updating the site, and while he is he temporarily needs to shut down the servers to make the changes. And when it is slow it maybe a peak time, and if the time is odd maybe it is peak time for a different timezone?
