Best server for rails 3

which will be the best web server and app server for rails 3

I don’t know about the best, but I have decent experiences with NginX
& Passenger.
I can send you some config files if you would like to take a look at

I did try with Thin for app server, but it Passenger does the heavy
lifting for you so it’s much more pleasant…

You might also try nginx + thin, varnish caching the pages, and perhaps
HAProxy for load balancing.
