why is Ubuntu slower then XP for my C++ app?
I have programmed in c++ a simple particles simulation using glut, opengl, std (math and list) functions.
I've compiled my code with gcc 4.1 with -o3 flag and using MMX, SSE, SSE2, SSE3 (-match = prescott) - so that it's optimized for my computer.
on windows i did the same using the latest MinGW port of gcc...
I set the frame rate to 33FPS, and count how many calculations per sec i get in the IdleFunc:
on Ubuntu it's 22000, while on winXP it's 27000...
both operating systems use the latest drivers...
