iphone - C++ code performance drop in iOS device -

-

i have implemented c++ code, , have run on windows machine. execution time takes around 220 milliseconds. ran same code on ios device (ipad), takes 1 second execution time.

what reason? how can achieve same performance on ios device? there way increase performance of c++ code on such device?

what ways increase performance of c++ code in ios?

i suppose average windows machine lot more powerful ipad many tasks.

that said, use instruments (part of xcode) profile code , see it's spending of time, maybe optimisations ipad become clear.
