[rabbitmq-discuss] Exchange matching performance

I seem to remember that direct exchanges dispatch much faster than
topic due to the complexity of the matching in the topic exchange.
Now that the headers exchange is out (or at least appears to be in the
disk paging branch), how does that perform?  It seeks like it would be
similar to the direct exchange, but with multiple possible keys.  I
haven't done any speed testing yet; I'm just wondering what the
expectation would be.
