As far as speed this Rom performs better than stock mainly due to the zip-aligned apk's which optimizes ram usage and the removal of what most would consider the stock sense bloat. The included Spare Parts app lets you speed up window transitions so things open almost instantly. Using this Rom in conjunction with SetCPU to enable "OnDemand" as well as set up profiles to underclock the processor when the screen is off will allow you to get much better battery life which is already good out of the box.
I am getting quadrant score of 1250-1350 with this ROM and Kingxklick BFS #4 with setcpu to ondemand with 245 min and 1075 max.
Is this about what you are getting?
