I am OC'd to 1.1 and I am only scoring around 1300. But thats just on this second release using P3's kernels. The first froyo release ran at much higher numbers for me. I can't seem to break 16 on linpack no matter what build tho. I haven't tried BB yet but might but in all honesty froyo has been running so smooth that I don't even feel like I need a speedy rom lol.
Edit: also I wanna say the second froyo release, when it first boots will crawwwwwwwlllll till I can get into setCPU. I know the first time you boot its gotta sync in everything so thats fine but I'm talking EVERY boot crawls. I have it set on boot now so it's fine but the first froyo release also didn't do that. I might re-load the original.
i had that too. it would take forever to boot up and be at a decent speed. i installed BB yesterday and it boots up a lot faster. and he has a script you can enter in terminal emulator (found in the market) that changes the boot animation and in turn speed up boot up time a little bit.
