Mike I've been there before, see my SO question:
http://stackoverflow.com/questions/7390285/webrequest-getresponse-taking-a-long-time-unless-defaultwebproxy-is-nulled
I really dont like this solution tho (yours and mine) unless its on a
per-customer basic (which I think it is in your case) as obviously this
can break outgoing connections completely.

Just in case it does come up for anyone else:
The AutoProxy detection process can take several seconds
(according to the docs)**, and is a blocking synchronous call.
The results MAY be cached for the current WinHTTP session but
this can be disabled via Group Policy.
In order to resolve this for us we just route around the
default proxy and go straight to the endpoint:
<binding useDefaultWebProxy="false">
I believe this solves the issue for our applications but may
explain some of the terrible network pauses we get here
constantly.

** Apparently this gets even worse if you're talking to an
endpoint that has no IPv6 address but you have IPv6 enabled.
