Remoting Performance and Auto Web Proxy .

The .Net Framework 2.0 has significant changes to its 
support for proxies including support for connection-
specific proxy settings, automatic proxy configuration and 
the ability to automatically refreshing proxy settings 
whenever the active connection changes. These features can 
be very useful in .Net Remoting but the auto web proxy 
feature can also affect performance. If you do not need 
these settings in your client it might be useful to disable 
them.

There are a number of ways to disable this:

 

1.       In Internet Explorer Open Internet Options, 
(either through control panel or the Internet Explorer™ 
tools menu), switch to the connections tab, and select LAN 
settings. Clear all checkboxes under automatic 
configuration. This will disable automatic proxy settings 
for the current user (note that this will not work for 
ASP.NET sites making outgoing web service calls because 
they run under a different user).

2.       Imperatively disable it by setting 
System.Net.WebRequest.DefaultWebProxy = null;

3.       In your config file bypass the proxy for your web-
server. You can also disable the default proxy altogether.
