We are using FMS to host a VoD site. We host FMS internally (we do not use a CDN). We recently installed an SSL certificate to alleviate connection issues for clients (they're networks either block or don't support RTMP), however we're noticing that when streaming in RTMPS connections are drastically slower (on the order of Mbps).

I know SSL causes some amount of over head but both client and server show almost no signs of exertion. Speedtest.net and a locally hosted speed test confirm that bandwidth is not an issue.

I'm really not a network guru, so I'm at a loss as to where to check next.

Do any of you have an idea why streaming media would run so slow over SSL?
