> Since our app server runs on a single core

Wow. Couple of questions :

* where is the server hosted and do you have a db server and maybe a cache server as well? What are the specs of the server?

* how much traffic does HN receive? Daily or monthly hits.

> Some big improvements which we've been working on for months will hopefully roll out soonish

If you're allowed to talk about it, what are the improvements?
