I stupidly forgot to consider that I had already rebuilt /bin/md5 with gcc4 on the AS800. The machines really are the same speed when you use the same executable. But gcc4 doesn't just speed up a silly md5 -t test. In fact, gcc4 produces so much better code that gcc4-built gcc4 itself is faster than gcc3-built gcc3: kernel "make depend && make": (PC164) gcc3: 91 min (AS800) gcc4: 80 min That is quite amazing. -- Christian "naddy" Weisgerber [email protected]
