  • When the content doesn't require any sort of encryption or security. – Fosco Feb 25 '11 at 21:33
  • This seems similar to the following question: http://stackoverflow.com/questions/4055131/what-are-the-pros-and-cons-of-a-100-https-site Hope this helps. – Jason Sendros Feb 25 '11 at 21:34
  • When the site is under so much load that it can not handle the extra ssl overhead (but in that case you will be looking for an ssl off-load solution) – rene Feb 25 '11 at 21:36

  • SSL costs more bandwidth.
  • SSL costs processor cycles, both on the server and the client.
  • Both things cost loading/processing time.

  • SSL doesn't cost always more bandwidth, because the encryption begins always with a compression (intending to make the compressed data more random, but making it shorter as well). Although it has some overhead, too - it depends on the case, which will be bigger. If you download a big, compressable file over https, you will experience big bandwidth shrinking. – peterh Mar 25 '14 at 11:31
