Installed all these three on pamela.santm.com and blog.santm.com which are running on wordpress 3.6 trunk. moved the dns details to cloudflare. While Pamela's hobby site did very well Google page test result our blog result was not great. Looks like the culprit is inbuilt gallery of wordpress which is re-sizing images and seving them on fly causing high server time. the command that helped me a lot is "mogrify -strip *.jpg" which is part of imagemagick tool kit and removes exif data from images.
