I got obsessed with speed, too. GWT reported pages on my site loaded on average in much longer than 3 seconds. It took me many months of learning and changing things around on my site, and finally GWT reports the pages load on average in 0.8 seconds, or faster than 94%. Yet, I have not seen it having any impact on SERPs, over all traffic, etc.
Speed is over rated. If you pages load in about 3 seconds, I'd say it is just fine. Go do something more productive than obsessing yourself with speed.
