Are there good resources for comparing performance of Stock Motorola ROMs vs. CM7.1? I'm looking for a good resource for which shows performance comparison - for Droid X - of Froyo 2.2 (stock ROM), Gingerbread 2.3 (Stock Verizon ROM) and any sort of Cyanogen ROM running on Droid X (presumably 2.3 based - 7.1?)

I'm NOT looking for first-person subjective accounts like these.

I'm looking for benchmarks - either as a direct single benchmark using identical set of installed apps; or better yet a set of collated averaged statistics.

I'm mainly interested in "normal business use" performance, not intensive graphics games one - I don't play anything heavier than Angry Birds. So if there is data from different benchmarks, whichever one approximates everyday business use would be preferred.

I would ideally like something which covers all 3 ROMs listed above (stock 2.2, stock 2.3 and CM7) but will be happy with any answers that only show pairwise comparisons of any 2.

NOTE: While the question is specifically about Droid X, I will accept an answer which shows a very good comparison of performance that illustrates a clear difference between ROMs across ALL comparable hardware (e.g. 1Ghz single-core, 512Mb memory, PowerVR SGX530 or comparable GPU) and makes a case that the difference should be easily carried over to DX.



Background: I am considering upgrading my Droid X from Froyo 2.2 (stock, rooted) to Gingerbread. I need to choose to either spend the time figuring out how to load the not-officially-supported CM7 from nightlies, or simply loading Verizon's stock Gingerbread ROM.

The 3 main things I'm concerned about as far as choosing ROM are (1) Stability, (2) Memory footprint, (3) Performance. This question only covers #3.
One baseline for measuring phone performance is the Quadrant Score.

Here is the quadrant score for Droid X with FroYo and Gingerbread.  

This site shows various quadrant scores for the Droid X with CM7, as well as unofficial versions of Gingerbread and FroYo.  

There are some debates about the usefulness of the Quadrant Score - hopefully since these are comparisons with the same model of phone, they would be useful.
