My site is http://www.TucsonGolfEstates.com which is running wp 3.5.1 on a custom theme. I've been trying to improve the speed of my site, but I'm still getting load times of 5-10 seconds where I used to get 1-2 seconds. My yslow grade is 85%, and pingdom gives me either a score of 88 or 92/100. I'm using w3 total cache with page/browser/database cacheing and cdn through rackspace (which is also my host).
I've tried every possible fix I could find on how to improve speed, but nothing seems to improve the loading time by much. Any suggestions?
