Try:

gnutls-cli -p 443 www.host.com -d 4711

and then type 'GET / HTTP/1.1' RET RET or whatever the URL that you
requested was.  This should do the same as wget does, right?  I may have
missed the initial part of this discussion, but as far as I recall it
was just regular downloading of some data over HTTPS.

Sure.  Using a process profiling tool like gcov/lcov may be useful as
well, to locate where the slowdown is.
