I'm not sure if anyone knows, but I can suggest - if you have the time and patience to investigate yourself - two tools that I'd use: freeware Synopse mORMot framework - has a time Logging profiler (synLog.pas) that will show the Delphi program internals times. (It has some known naming clashes with some Delphi internals though) Magenta Systems Internet Packet Monitoring Components - should allow you to check the network traffic coming from your SSL setups (Delphi or otherwise) from a separate program and will allow you to try and do some deeper investigations as to which part of the communications is taking the most time.
Not saying it will be easy and the tools have their own learning curves and need for tweaking too.
