Hi!
I noticed yesterday that a single HTTP request to localhost takes
roughly 1s, regardless of the actually served data, which is way too
long. After some digging, I found that the problem lies in
socket.create_connection(), which first tries the IPv6 ::1 and only then
tries the IPv4 127.0.0.1. The first one times out after 1s, causing the
long latency.
What I'm wondering is this:
1. The server only serves on IPv4, changing this to IPv6 would probably
help. However, I wouldn't consider this a bug, or?
2. I don't even have any IPv6 addresses configured and I'm not using
IPv6 in any way, so why does it try those at all?
3. Of course I can optimize the code for IPv4, but then I would be
pessimizing IPv6 and vice versa...
Any other suggestions?
Uli
Notes:
* Using 127.0.0.1 as host works without the delay.
* I'm using Python 2.7 on win7/64bit
