You can also have a look at pystone benchmark results (a quick googling around gave me e.g. http://www.levigross.com/post/2340736877/pystone-benchmark-on-2-6-2-7-3-2) > Otherwise yes, let's get gently beyond 3000. > > -- > Jan > -- > devel mailing list > devel@xxxxxxxxxxxxxxxxxxxxxxx > https://admin.fedoraproject.org/mailman/listinfo/devel -- Regards, Bohuslav "Slavek" Kabrda. -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel
