Interestingly, reducing from the max open file descriptors from 8192 (my default) to 512 halves the runtime and solves the regression:
$ ulimit -n
512
$ ./python bench_subprocess.py
pid: 31631
Time: 4903.8 ms
So, even though implemented in C, the file descriptor closing logic is still quite costly! |
