Well, as I've shown in issue 24076 (I'm copying the numbers here), even simple arithmetic expressions can benefit from a free-list. Basically anything that uses temporary integer results.
Original:
$ ./python -m timeit 'sum(range(1, 100000))'
1000 loops, best of 3: 1.86 msec per loop
$ ./python -m timeit -s 'l = list(range(1000, 10000))' '[(i*2+5) // 7 for i in l]'
1000 loops, best of 3: 1.05 msec per loop
With freelist:
$ ./python -m timeit 'sum(range(1, 100000))'
1000 loops, best of 3: 1.52 msec per loop
$ ./python -m timeit -s 'l = list(range(1000, 10000))' '[(i*2+5) // 7 for i in l]'
1000 loops, best of 3: 931 usec per loop |
