Android performance

Hello,

I have been setting up a little testgame with the “Million Tile Engine”

Its just a simple 50x50 map… But the performance is acting really weird

I tested on some phones,

single core 800 mhz (xperia miro) : runs smoothly
Dual core 1500 mhz : runs laggy

How is this possible?? The miro has 4.04 and the other one got 4.2.2, could this be it as it also runs laggy on other fast phones with the same version and a galaxy s1 with 4.04 runs smoothly too…

Does anyone notice the same with their games??
