Ruby performance

[blaz boy]

i made an application that makes chatting rooms for websites with a new concept (http://tahadth.com)

that website backend (the chatting server itself) is made using Node.js

i choose it for it's great performance and response time and that is could take

a huge number of connections (the only limit is i discovered is my limit is 1GB of memory-that is V8 limit)

i discovered rails (i like to name it a discovery :D ), and i really would like to develop that application with rails 

(again), 

the QUESTION is , does rails has that power in it ?

- the speed, memory limits, concurrent connections, rails design.

given that i expect to have more than thousand of concurrent connection (yeah i'm optimistic person)
