SSL/TLS/HTTPS sites are very slow in a C#/.NET WebBrowser control, but fine in Internet Explorer

Background

I'm modifying AutoWikiBrowser to work with a MediaWiki site hosted on a secure server. I allow the user to login manually via a WebBrowser control in a C# application, and then save the stored cookies for use in HttpWebRequest's.

The Problem

The problem I'm having is that any site which uses SSL/TLS (https:// urls) takes an incredibly long time to load, often timing out. I've tried this not only with the MediaWiki site in question, but also other secure sites like PayPal and secure GMail.

Out of curiosity I tried the same https sites in the help browser of Visual Studio, the [VB WebBrowser Sample][2], and the [WPF WebBrowser Control Sample][3] and they were all dead slow. These same sites perform just fine in Internet Explorer 7 (and of course Firefox).

The Question

What would cause SSL/TLS sites (https urls) to be very slow using the .NET WebBrowser control, but load fine in Internet Explorer?
