I can attest that the timings are extremely unstable with regard to what's imported where and their order. For example, why does sage.misc take so long? Because it imports nearly half of sage.rings. Later modules will be fast or slow depending on what's been sucked in earlier. This is one of the reasons it's so hard to debug circular imports and startup time. https://plus.google.com/106060403099461455118/posts/KhGipCThNtN http://trac.sagemath.org/sage_trac/attachment/ticket/11749/11749-unneeded-imports.patch#01155b7d76b047a334c460569e9e8c54 http://trac.sagemath.org/sage_trac/ticket/11762 - Robert -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
