[Pythonmac-SIG] socket.getaddrinfo problems

[Dudley Carr]

Hi,

I have an RSS reader written in Python that's performing poorly on OS X Panther. 
I've managed to track it down to getaddrinfo. I tried the same code on Windows 
with Python 2.3.3 and the look-ups are a fraction of what they are on OS X, so I 
don't believe it's a problem with my network configuration.

I've run the code snippet below several times on different domains with the same 
results. Can anyone else confirm the timings that I'm getting below?

Regards,
Dudley

 >>>import socket,time
 >>> def getaddrinfoTest(count):
...     for i in range(count):
...             start = time.time()
...             socket.getaddrinfo('yahoo.com', 80)
...             end = time.time()
...             print 'time =', end - start
...

 >>> getaddrinfoTest(20)
