OWA Performance with SSL

Hello,

I'm running Exchange Server 2003 on my server and Outlook Web Access is a crucial aspect of my need for it. The problem is when I enable SSL for the OWA page in IIS 6.0, I get a massive performance decrease. It goes from instantly appearing to taking almost a minute from the initial authorization to OWA fully loading.

I was wondering if anyone else had any trouble with SSL enabled web pages with a certificate from a Windows 2003 CA. I really need the page to be secured by SSL so leaving it off really isn't an option.

Thanks,

Andrew
