Hi All, I realize that this is only tangentially related to Sage, but it was Sage development that I started off on when I got side-tracked by how slowly it was running on my brand new Mac Pro. After much tracing, I found that the culprit came down to slow GMP (due to GMP being compiled with mostly generic C code for the Intel Mac platform). After tinkering with compiler options and re-writing three assembly functions from the x86_64 code base, I've managed to get GMP running very nicely on my Mac Pro. It should also run nicely on other 64bit Intel Macs. Currently I get "near-Opteron" speeds from GMP on my Mac Pro (which is a significant improvement over previous Intel chip performance). So, for any who are interested, you can download the patch from my website, http://www.math.jmu.edu/~martin
