Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

I know it is a vague and ambiguous question.

I want to know just out of curiosity. How many instances of a rails app can I host on server with 256 MB RAM [Cheapest option on Rackspace]?

Assumptions - The app is very simple with 100-200 CRUD operations/day. - Database server is on a separate server.

How much RAM does one instance take? What are the VSIZE/RSS figures in top? –  Jason Jun 27 '10 at 13:43
    
I mean, what are the figures after your 1 instance has started up, and has serviced at least 1 typical request? –  Jason Jun 27 '10 at 14:18
