Always use fixed DH parameters created with 'dhparam -C',
don't dynamically create them. This allows using ssltest
for approximate performance comparisons:
$ time ./ssltest -num 50 -tls1 -cert ../apps/server2.pem \
[-no_dhe|-dhe1024dsa|-dhe1024]
(server2.pem contains a 1024 bit RSA key, the default has only
512 bits.) Note that these timings contain both the server's and
the client's computations, they are not a good indicator for
server workload in different configurations.
