In practice, most of the round-robin'ing will be happening on caching
servers that are outside your control.  So I don't see what you're trying
to accomplish by increasing the entropy on your server.

Your testing is almost certainly not approximating real-world conditions,
when clients will be coming from around the Internet (unless the
application you're working on is an internal-only server).
