Yeah, I did - it doesn't make any mention of xeon, but I found some docs using google that indicate that -march=pentium4 is the optimum choice for a Xeon system. I tried it with my Debian woody box, but it failed, I'm going to try again after updating to sarge which moves gcc from the old 2.95.4 release to 3.3.something. Josh
