The Fast-CGI difference
Having got my Rails CMS working under CGI last night, this morning I switched it to dispatch.fcgi and it really does make a serious speed difference! Running with dispatch.cgi the app was pretty slow, taking a few seconds for each page to load, while using Fast-CGI it's near instantaneous. I'd never actually tried using normal CGI as everyone says you should use FastCGI and now I see why. So, use Fast-CGI! :D
