Does SSL cause a lot more bandwidth?

Question

I know SSL has a performance hit on your HTTP communication in terms of speed but is there much of a difference in the amount of data transferred?

ie, If a mobile device is paying a lot per kb, is there a huge difference? Does anyone have an estimate of how much of a difference?

Thanks for the help!

Answer 1

No, there is not much of a difference, neither in terms of "performance" nor in terms of bandwidth.

According to Google, a company one would hope is a reliable source on large-scale networking, the network-bandwidth overhead is less than 2%.
