4.2.x roms are slower than firomi''s and sharkdroid - i checked PA, cm10.1, cm10.2, aokp and what else..
What makes me wondering - 4.3 roms should be faster, but they are not. 2D is VERY laggy everywhere(gui, games, whatever).
Do you have any idea why?
I am unable to figure out why, massive tweaking is not helping in that cases at all, weird, these roms are really slow...
If that is the case, then you probably could use some rom using this new kernel as a base in your porting experiments.Because SharkAndroid and firomi roms used new,optimized kernel and drivers.
(that is, if some stock firmware or these custom ones using it (kernel+modules) work in your device)
I say probably because I have heard about problems when using last springs/summers stock firmwares.
It could be that Troy's ROMs don't work with those new kernels/modules, but that doesn't mean that some older/newer ones wouldn't work.
(the other possibility of course is, that they haven't done all things totally "by the book", or it just needs some tweaking to work)
