I cannot repro. On my ubuntu virtualbox I get:
before:
kristjan@kristjan-VirtualBox:~/cpython$ ./python -m timeit -s "from _thread import allocate_lock" "allocate_lock()"
10000000 loops, best of 3: 0.0768 usec per loop
kristjan@kristjan-VirtualBox:~/cpython$ ./python -m timeit -s "from _thread import allocate_lock;l=allocate_lock()" "l.acquire();l.release()"
1000000 loops, best of 3: 0.209 usec per loop
after:
kristjan@kristjan-VirtualBox:~/cpython$ ./python -m timeit -s "from _thread import allocate_lock" "allocate_lock()"
10000000 loops, best of 3: 0.069 usec per loop
kristjan@kristjan-VirtualBox:~/cpython$ ./python -m timeit -s "from _thread import allocate_lock;l=allocate_lock()" "l.acquire();l.release()"
10000000 loops, best of 3: 0.182 usec per loop
I did this a few times with consistent results. But virtual machines aren't the most stable of beasts. Perhaps someone with a proper unix box can test it? |
