is (equal(1,exp(256*(x+1)))); which indeed can take quite a while. In fact, profile data indicates nearly all time reported is spent on that statement. The relevant routine is test_relation_maxima in sage/symbolic/relation.py . The routine could use a facelift (it's doing a lot of strings-based stuff that doesn't need to be done strings-based anymore), but the bottleneck for this example seems to be entirely in maxima. -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
