The short answer is that you need to benchmark using various
configurations. You have a particularly bad problem, what with
the per-request encryption beating on the CPU's, and the large
file size beating on the network (and putting your servers at
the mercy of the clients).

Pushing all of the solutions downstream like this instead of
coming up with a better front-end is going to cost you. This
all just screams for a more elegant solution than just asking
apache to stick it's finger in the dike.

Good luck.
