Can you double check that data as I redid the test and the differences didn't seem to be there: 8.85, 8.92 without the patch and 8.45, 8.49 with the patch. > Thus (if I understand you) rewriting the product_by_generator_on_basis > method in > iwahori_hecke_algebra.py might help. I played a little around this morning, and indeed one can reduce overhead inside in the product method for algebras_with_basis. But this still doesn't improve your computations on the Hecke algebra. The problem in there is that most of the time is taken by the product_on_basis method and the submethods called therein. The reduced word and the descent set is computed multiple times and simples are applied - that takes a while... To me it looks like the speed in there is not a question of general speed improvements for CFM or algebras_with_basis...
