I'm using POW as a proxy to my local dev server in development. That gives me nice local *.dev domain names. However I've noticed that it takes 10 seconds to load a singe page in Chrome. Of course, I thought, It does like 80 requests as each asset is served as a separate file in development. But after investigating it a bit more DNS lookup for each request was 3 seconds and for some reasons it was like that for every single http request.
