FYI, during our testing in the run up to jabber.org this time, I
happened to notice what an impact DNS is to S2S setups, and that
running a local caching resolver is a huge help to an XMPP service.
It helps in two ways:
- It means that previously known queries respond much faster.
- It means bandwidth cost for connection establishment is much lower.
Of course, for most services it's not going to be a massive impact
(and for big public deployments, you've probably already done this),
but I thought I'd mention it while I remembered.
