I'm running your 2.4.1 ROM with Wildmonk's 01/06/2011 kernel, using SetCPU to OC to 1152, and I'm seeing nowhere near the performance you show on your screencap in post #1. Your phone is running 1888, and I'm running about 1000 points below that in the 800 range.
Also my Linpack scores are pretty low, around 33.
Any thoughts as to why my performance is so poor?
I think Rod fixed the Quadrant issue on build 2.5 or 2.5.1, I forget but it was recent. I did a quad test and came up with around 1500 so it was indeed fixed at some point after 2.4.1.
EDIT: Check the changelog it was on build 2.5.1 when he fixed the Quadrant issue.
