Hi all, we recently noticed that the IntegerMatrix class from fpylll is (on our hardware) much slower in sage9.x, than it is in sage8.x.
Please consider the following code snippet: import time from fpylll import IntegerMatrix dim = 30 bits = 10 A = IntegerMatrix.random( dim, "uniform", bits = bits ) B = IntegerMatrix.random( dim, "uniform", bits = bits ) start = time.time() C = A*B stop = time.time() print( "Multiplication took %f seconds." % (stop-start) ) We tried running this code in Sage 8.1, 8.9, 9.3 and 9.7. In the 8.x versions, the multiplications takes less than 0.2 seconds. In the 9.x versions, it takes more than 6 seconds. Any ideas?
