Thanks for the fast response, Reborg.

I'm not sure what type of cache I'm using. Is there a quick way to find out? It's whatever is default when using SimplePie, because I haven't changed it.

Could you please describe how I might use the "ab" apache benckmarking tool? I have not heard of it before and would not know where to begin. If you could provide an example of how I would use that to pass the url through, I would really appreciate it. Again, thank you for the reply.
