Why is SSL slowing down my Web Service response?

I have a full-scale Website running with ColdFusion 8 on IIS 6. The website performs up to expected standards - a simple HTML page loads in a matter of milliseconds.

I am adding a couple Web Services to this website. When I call the Web Services over HTTPS they are extremely slow (4-5 seconds) compared to HTTP (milliseconds).

To confirm that this is not the actual functionality of the Web Services, I created a test Web Service CFC method that simply returns a one-character string. When running it over HTTP, it returns in 16ms. When running it over HTTPS, it takes any where from 4-5 seconds to respond.

Why are these few Web Services so much slower than the rest of the website which runs on HTTPs with no performance issues?
