Extremely slow speed on my site using codeignitor... is this normal?

It's clearly a server side issue.

Although your homepage is almost 2Mb in total uncompressed, it has no problem arriving here in a timely fashion (I have a 100Mbps pipe to the internet).
Firebug tells me that it takes 3.07sec before the reponse on the GET www.coupunbunga.com is received. That corresponds with the processing time reported by the profiler.

I had to swallow though when I saw the query list. Ouch. I see a lot of repetition, and lots of them queries with multiple joins. Clearly a sign of a design issue, one that might be difficult to fix...
