[pypy-issue] [issue942] CPython 2.7 faster than PyPy 1.7 in select/socket/ctypes script

[Michael Schurter]

New submission from Michael Schurter <m at schmichael.com>:

(Only works in Linux... may work in OSX with the socket type changed.)

Running "punish_logd.py 1 25000000 log.sock 0" returns the following when 
running simplelogd.py with Python vs. PyPy:

CPython 2.7: Sent 2500000 messages in 38 seconds (64318.894760 per second)
PyPy 1.7:    Sent 2500000 messages in 48 seconds (51576.415662 per second)

I removed the output file between runs.

simplelogd.py requires mmstats master to be installed:

With mmstats installed you can run "pollstats -p simplelogd. messages 
/tmp/mmstats-*" to get messages per second output.
