After being jealous how my mom's Optimus L9 with 1.0Ghz dual core OMAP cpu felt so much faster and smoother than my phone, I decided to clean it up. Not actually because of that. Just got annoying any time one of my launchers updated it made me choose the launcher. I had about 6 installed, Nova, Xperia, Zeam, ADW, Launcher pro, etc. Now that I removed all those launchers my phone feels about 2x as fast. I guess they were running in the background and slowing things up. Incidentally the IO scores for quadrant and antutu on my mom's Optimus L9 are much better than my spectrum. And it actually benchmarks better than the GNex largely because of IO. Though Samsungs in general seem to have sluggish IO.
