fast_convolute():
old: 791277 decicycles in fast_convolute(), 65536 runs, 0 skips
new: 775519 decicycles in fast_convolute(), 65536 runs, 0 skips
fast_convolute2():
old: 532707 decicycles in fast_convolute2(), 65535 runs, 1 skips
new: 518874 decicycles in fast_convolute2(), 65536 runs, 0 skips
Applied.
