Recently my site is very slow to load for viewing and also with the admin (which I guess shouldn't be an issue regardless of which theme I'm using).

About a month ago I got it working really quickly with w3 total cache but now its much slower.

I've tried all of the usual things like turning off plugins and cache but nothing doing. I also upgraded to the latest version but that was even slower and generated a lot more queries!

I'm currently using 3.5.1

The site is www.shaunedwards.com
could also try an inner page like http://www.shaunedwards.com/weddings/album

I'm getting 20-30 ish queries but a load time of 5+ seconds. I want to try and pin it down to whether its my host or maybe even ISP.

yeah pretty pleased with the 96 page speed I spent a long time with w3 total cache.

The home page will take a short time as there is a large rolling banner style slideshow on it. As I'm a photographer there have to be pretty big and good quality. Other inner pages should load a lot quicker.

I have set the cache to be primed 7 pages every 15 minutes - Its not a huge site so most of the pages should be primed within an hour.
