What makes ARM cross compilation faster on the ARM?

Hi Everyone, Normally, cross compilation just makes the compile time dramatically less but keeps the program performance the same. Is using the arm-gnueabi toolchain making the performance difference on the ARM, or is it the flags used like -DENABLE_NEON=ON and other optimizing flags?


PS: I'm using an ARM Cortex A9 and OpenCV 2.4.9
