Radiant CMS is slow for me on Dreamhost. Can take up to 3 minutes to load a page. Never less than one minute if hasn't been loaded a while. A straight HTML page takes seconds.
Is this normal or have I done something wrong?
I've different installations of Radiant, with and without embedded Rails. Slow either way. After initial loading, reloading can be in seconds, although slower than HTML. This site will not generally get much use. It seems that once the site has been loaded, it loads faster. I don't think it's caching on my machine that's doing it, because it's a small page with one picture. But I'm not an expert, and haven't done any testing getting rid of the cache, etc. The main problem is that if a stranger loads it, they'll likely think something is wrong and give up and that's not acceptable.

I don't think Radiant is inherently slow because some Radiant sites are fast.
