Very very slow when computer connected to VPN

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Connect to any VPN
2. Run the cefclient on your machine(not the virtual machine)

What is the expected output? What do you see instead?
Speed should be normal as I have completely disabled proxy check in 
FindProxyforUrl method. My FindProxyforUrl looks like this:
bool FindProxyForUrl(const GURL& url, std::string* proxy_list) {

  DCHECK(_Context->request_context())
  int rv = net::OK;
  return rv == net::OK;
}

What version of the product are you using? On what operating system?
I am on revision 82. It gave the same issue on Windows XP and Windows 7(32-bit 
and 64-bit).

This may be related to issue 81. Please try with revision 116 which fixes that 
issue.

This may be happening as CEF always uses IE system proxy settings, see issue 
600.

See also this thread, it was noticed that IE proxy can slow down even loading 
local 127.0.0.1 content: http://magpcss.org/ceforum/viewtopic.php?f=6&t=2586
