My point is that while there is increased occupancy just from having the SSL connection, as you'd expect, there is massively increased occupancy while a GET request is outstanding on the SSL connection.  That's what I find surprising, because I'd expect that on an individual request you'd need a bit of extra memory during the decryption of the request and the encryption of the response, but not in between the two.  I'm wondering if anyone knows why that is and whether it's possible to reduce it.
