Basically, you specify that your rails app run "8 processes" at once and each will use one core. The way I do it is by using phusion passenger [in my case, with nginx] and you may get it to work like

passenger_max_pool_size 8

passenger_max_instances_per_app 8

If you want to make sure your cores are all busy [and have enough RAM] then possibly set them to size 16'ish

Multicore servers only boost performance if the rails app is running in multithreaded mode of in multiprocess mode. Ruby currently supports 'green' threads, which are lightweight and not true processor threads. Rails has support for multithreading, but gem support could be lacking and would probably be unstable for production. To make the best use of a multicore server, running a web server like unicorn or passenger, which can spawn rails processes per core, would provide you the best performance boost
