Bueno aqui dejo unos benckmarks que realizaron con algunas ROM. Esto fue extraido del foro de XDA.
Summary;
DCD 4.1.2 had an avg. of 1 Mb Free RAM available over all other ROM,
Keep in mind DCD ROMs has less running processes .. still very impressive
Seeing over 27MB of RAM before I loaded the screen capture software ..
Available RAM = DCD 4.1.2
Best write performance = WM6.5
Best overall write performance = WM6.5
Best read performance = DCD 4.1.2
Best overall read performance = WM6.5
Best read/write (copy) performance = DCD 4.1.2
Best overall read/write (copy) performance = WM6.5
Best CPU performance = WM6.5
Best Overall CPU performance = DCD 4.1.2
Best Graphic performance, DCD 4.1.2, R4R and TR 1.3.2 shown
100% the same performance, WM6.5 and DCD 3.2.6 being slower..
Overall Winner IMO WM6.5 reason being, the additional process running
takes up both memory and CPU, plus the fact its M2D ready!!
Also Note .. R4R and TR 1.3.2 are both base on the DCD 3.2.6 ROM,
DCD 4.1.2 is more on par with WM6.5 ROM.
Final note R4 Reloaded fail the (Arkabal frames per sec. test) feeling is something to
do with direct-draw not working correctly .. so for R4R I had to skip that test..
