I came some time ago with an SSL slowness that I didn't figure out
(described above).
I have just found what the problem was: I was using the LinWiz iptables
firewall builder, and this one did set by default to have a limitation for
synfloods at 1 syn per second (at the end of the script).
This, used with SSL, makes the HTTPS connection transfer speed being very
very slow, but not for the HTTP connections.
Now I incremented it to 50/s and 100 burst limitation, and all works very
well.
For those that this might help..
Daniel
