I also ran some tests at some point to compare GMP and MAGMA's integer multiplication, as I started to suspect that was part of the problem. Here are the results I came up with, which are unfortunately not going to be accurate at the low end: http://sage.math.washington.edu/home/dmharvey/magma-vs-everyone/ZZ- mult/graph.png http://sage.math.washington.edu/home/dmharvey/magma-vs-everyone/ZZ- mult/readme.txt http://sage.math.washington.edu/home/dmharvey/magma-vs-everyone/ZZ- mult/comparison.txt David --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-devel@googlegroups.com To unsubscribe from this group, send email to [EMAIL PROTECTED] For more options, visit this group at http://groups.google.com/group/sage-devel URLs: http://sage.scipy.org/sage/ and http://modular.math.washington.edu/sage/ -~----------~----~----~----~------~----~------~--~---
