Is there any bandwidth overhead on using SSL on a TCP connection? I understand, of course, the processing/memory usage overhead in encrypting and decrypting packets, but as far as bandwidth is concerned, what is the difference, if any?
For example, given a XML file which is 64KB, will there be any tangible difference in the transfer size of the file over HTTP vs. HTTPS? (Ignoring mod_deflate
and mod_gzip
, of course)
