Right, and on that page is says: "Some experimenters suggest that code compiled using -Os (compile for size) will run faster than -O3 (compile for speed) because the VIA processors have very small cache and the smaller code will improve the chances of cache hits. I haven't seen any numbers to confirm this - maybe someone will try it and let me know if it is true." I'm curious if anyone has tested this with myth
