瞎扯淡 Chicago Boss: Start small, dream big
We love Rails, but we believe that Ruby is the wrong choice of platform on which to build a simple, fast, reliable website. The alternatives aren't much better: the JVM, V8, Python, and Perl all eventually run into the problem of dog-slow server-side templates.
Web developers usually "solve" the problem in a number of ways: buying lots of hardware, hiring a big ops team, implementing complex nested hierarchical cache structures, ripping out features, and moving to a "thick-client" architecture that takes forever to load. But there's a much simpler solution: it's called respecting the RAM.
