I just found this thread while uploading my first Atari supporting version of vbcc6502. Of course I downloaded the examples and compiled them with vbcc.   Not sure if everything is correct as I am not familiar with the Atari, but with an emulator I get the same results for the posted binaries of gcc and cc65. So here are my results: cc65: 474 ticks gcc: 378 ticks vbcc: 165 ticks (vc +atari -O3 -speed dhry*.c -o dhrystone-vbcc.xex)   For md5: cc65: 811
