Almost every morning, and sometimes even during the day/evening, there is a huge slowdown, so much to where the site is inaccessible for a while. The server had problems when I tried setting up PHP-Nuke, in that every time the configuration was updated from the admin menu, the entire configuration would die and I would have to reupload the original configuration file. Basically the server is just not all that optimally configured.
I have nothing against the host business-wise at all, as I understand they have dozens of servers to manage, so they are not always able to address the small issues with each one. But problems do exist anyway.
Not too long from now, all these problems should stop, however, and that's not a bad thing, That's a Good Thing™
