hey all,

i have a game developed with corona, it works really well on simulator (cuz it has more memory ofcourse :) ) but on the device (iphone 4) it is laggy.

i tried to see the memoryusage but i dont know if its too high for an iphone device or not.

in my game every enemy object based on 1 sprite. and the sprite is only 15 kb. these objects has their own collision and sprite eventhandlers. i think the problem is in these functions. but i dont know how can i imporove the code.

so my question is, how can i test my application's memory usage if its too high or not ?

thnx for all replies.
