Usually when you want to archive more performance ex. in mongrel or  
thin( i dont know how the webrick, ebb,… works) in powerfull machines  
ppl start new process in other ports and direct the requests for each  
process.  
Why do this? Isnt better start new threads in only one process?

‘Multi-core’. You can shift multiple processes around on multiple CPUs.

And then there’s the nastiness of thread-blocking. In such a case, a  
process possibly has to wait for a thread to complete. That is not  
really desirable, if you have more than one concurrent request.

Also, if one process gets into a deadlock, it doesn’t take your whole  
web-server with it.
