Thank you very much! :)

Why not use Nginx as a frontend to Unicorn? It should reduce your memory footprint even more.

You know, every byte of RAM counts on a micro instance :)

Nice one :)

You're right, Nginx consumes much less RAM (and it's generally faster) so it was our first choice on this micro instance. Unfortunately we need to have running another monitoring software that depends on apache2 and after some usage calculations we determined that Apache was a valid "lightweight" frontend for us.

Anyway, setting up a Nginx frontend for Unicorn is trivial too, it would be a great post update ;)

Thanks for the advice!
