I have a theme I generated from Artisteer 3. It allows you to customize a lot of things without getting too dirty in code.
Now that it's up and running I find it sluggish. In my opinion it has far too much js (taking between 2 and 3 seconds to load) and unnesesarily uses images for format (ie for round corners). the css is huge and takes a good 3 secs to load as well.
I need something quick that I can give a similar look to what I have here http://www.imailroom.ca
Any ideas on a better theme? Maybe one where I can use a child theme for the modifications.
