The slowness kind of comes and goes. Most of the time it is fast, but every so often a traceroute will show a router down the line having issues (losing packets, high latency, etc).
Not exactly sure what to say, other then to try it a few minutes later. One of these days when I get some time, I will be recoding the site in CGI or PHP. This will then allow the possibility of hosting the site elsewhere if needed.
