I think I know what the problem is. It may not be the forums that load slowly, but rather the ads that load slowly. When loading a page, there is a long delay, and then half the page loads suddenly, right up to the middle of the page ad. Then there is another long pause, then as soon as the ad loads, the entire rest of the page loads quickly. Since that has been the case every time, it appears that it is only the advertisements that slow down the loading. Perhaps a change could be made to the system allowing the entire page to load right away, with spaces for the ads. Then, let the ads fill in the spaces when they are finally ready. The ads would still appear, but they would no longer hold up the loading of the forum page itself.
