Another poster seemed to > indicate that the i386 release would run just fine on a quad core chip. Yes, i386 will run just fine on a 64-bit Xeon. And no, there isn't an easier (well, one could argue it's easy, but tedious) way to "convert" to an amd64 release. > Would there be a major performance gain with amd64 over that of the i386 > build on a Xeon Quad Core? It depends entirely on your workload. Some things benefit, others may actually slow down. One example that seems to benefit in general is multimedia type applications (e.g. media encoding/decoding/transcoding). Josh
