I am very interested in learning a Ruby on Rails / Django type web technology but am currently using Windows Server 2008 (for .Net web applications.) I have read that RoR is not very performant on Windows.
Would it be unadvisable to create run a beta web application in RoR on a Windows Web server as far as performance is concerned?
Would Django or another similar technology be a better choice? Can you be a "happy, productive programmer" and still use a Windows Server?
(Note: I actually do enjoy heavily modified Asp.Net / C#. I'm looking to try some different stacks that might be fun and productive from the start.)
