strange problems with urllib2

[jdonnell]

When I run this code on windows it runs quickly (about a second per
image) but when I run it on linux it runs very very slowly (10+ seconds
per image). Is this a bug or am I missing something? On windows I tried
2.4.2 and 2.4.1 on linux i'm running 2.4.1

print 'starting'
f =
urllib2.urlopen('http://site.heavenlytreasures.com/images/e6115.jpg')
outfile = open('e6115.jpg', 'wb')
outfile.write(f.read())
outfile.close()
f.close()
print 'finished'

That kind of thing is often caused by DNS problems. Are you running named
on your Linux machine? Have you double-checked that the named
configuration and /etc/resolv.conf is correct?

How long does it take for you to do this:
wget http://site.heavenlytreasures.com/images/e6115.jpg

I'm running a 1999 vintage 250 MHz Compaq
with Debian Gnu/Linux & Python 2.3.5 ....

The following version of your code
worked very well here ....

I haven't checked them, but will do it now. However, I don't have
problems with anything but python. I can download that image in less
than a second with wget or in my browser. I know that I had ipv6
problems before. I had to turn it off because of my nat router so I'll
look into that sort of thing.
