since I got back my trusty old Orange San Francisco yesterday, I thought it would be interesting to do some ROM comparisons, investigating if there is such thing as a "performance build".

Procedure every time was: Complete wipe (including /system), flash ROM, first boot, one-minute-wait, reboot and then start the benchmark. No gapps or other stuff, internet connection off (apart from some seconds to submit the quadrant score, since it won't display the values otherwise).
So, without further ado, I present: STATISTICS!
To visualize the results (and, to make it look a little bit more like science than nerd-spending-hours-doing-useless-nerd-stuff), I also created some charts:
As you can see, the best score is achieved by the good ol' CM9 build, followed not by CM10 but (surprise!) 10.1. The more recent versions both perform worse.
The detailed Quadrant scores:
Processor and memory are more or less equal in the first three versions, but especially the CPU performance really degrades in Android 4.3 and 4.4. Maybe that's why KitKat feels kinda sluggish even just scolling through the menus.
Interestingly, the I/O was significantly better in ICS than in the later versions.
And we get to the CF-Bench Native and Java results:
ICS scores first place, followed by the second JB release. Java performance is kinda bad in KK (almost half the score of CM9)
Last, but not least: The graphics performace!
From 4.0 to 4.2, 3D got a bit better while 2D gets just a tad less frames. Notice the huge drop at CM10.2, for both dimensional layers. KitKat performs average.
So, what do we learn?
CM9 is still the performance king, because of the +30% I/O throughput compared to the newer versions. Apart from that, the ROM of your choice should be KonstaT's CM10.1 build, which even offers a gain in 3D framerates (but not that big).
Kitkat and the latest JellyBean should be avoided, since there is a big gap in CPU respectively memory / 3D performance.
What this small excursion into the land of modern communication devices didn't cover: Stability, functionality, battery consumption, and, ironically, communication. I don't even know if the phone speaker works (it didn't in some CM10 build for my LG2x. Took me weeks to notice.)
I personally will give CM10.1 a shot as my daily driver. A little bit more modern than ICS, but not much slover. Also needs only 160MB /system TPT ;)
Have a nice day!
