Heh, heck my db and app live in the same data center, and the latency is more than 30-40 MS.

Really? That seems enormously too slow. Even over the internet, I'm within 5-10ms of most things in the bay area.

If you have a dozen slow (100us) switches, three slow (2ms) routers, and 500 kilometers of fibre (2ms), you should still be under 10ms each way. And that's enough gear to cross some countries.

I'm curious how you can do much worse than this in a data center. Maybe some pokey "application firewall" or massive buffer bloat?
