Performance difference SOAP with and w/o SSL

Has anyone compared the same archive job with and w/o SOAP over SSL? What is your experience?

I realized a big slowness archiving with SSL in two environments. 20 to 50 times slower. In my opinion, 50-100% slower can be acceptable.

Support  confirmed it in their lab.

Here are couple of examples. Just using the same Profile (All Items in Mailbox) and switch SSL on or off.
