I just rooted last week and immediately flashed CM7 RC2 and there were a lot of lag issues. Flashed SD 5.5 today and I am loving the speed so far. That's the main reason I rooted. Only one bug I ran into. 3g would not connect after the first call I got after flashing. I saw a post to somewhere to put on airplane mode and then switch back and that worked. Got another call later and phone went back to 3g automatically
