Are you using HTTP 1.1 with connection reuse? Check that both your
client(s) and your server are happy to use 1.1, and you may be able to
cut down the number of parallel connections.
Alternatively, since fixing it at the browser seems to be hard, can
you do something ridiculously stupid like... tunnelling insecure HTTP
over SSH? That way, you establish the secure tunnel once, and
establish a whole bunch of connections over it - everything's still
encrypted, but only once. As an added bonus, if clients are requesting
several pages serially (user clicks a link, views another page), that
can be done on the same connection as the previous one, cutting crypto
overhead even further.
