Performance Trade-Off with Encryption

Posted by Webmaster in Uncategorized

My previous post about encrypting all our our web traffic didn’t generate a ton of feedback. But the feedback it did generate was unanimously in favor. My only reservation is the performance hit we’d take (and a bug with IE refusing to stream our videos on an encrypted page, but I’m working on that). So today I ran a couple tests on our home page.

I don’t have time for an in-depth analysis today. But the gist is an 18% increase in first visit load times and an 81% increase on repeat visit load times. I may need to revisit my gzip setup since apparently my CSS and JS files aren’t getting zipped for HTTPS requests. As I make progress on debugging IE (which needs to be a 30% line item on my job description) I’ll look into ways to address the gzip issue and to further minimize the performance losses of encryption.
