Didn't have the chance to see the speed in this ROM, because it keeps crashing on my device.
CyanoGen mod app crashed and after that the touchscreen didn't work properly (even after reboots)
Changing the brightness level from statusbar -> crash.
Putting the Max CPU to 998Mhz or more -> crash.
I'm reverting to the default flavor of CM7, sadly, as I was interested in the new kernel and the speed-ups of this ROM - as long as the things that were removed perfectly suited my tastes.
Hope you will make this more stable in future.
Can you please provide a full logcat ?
Do you use CWM or TWRP ?
