The writer's argument pretty much boils down to the claim that java will be faster than ruby on rails even more than now. For technical reasons why he claims this, read the article. I don't know enough to know if his technical claim is true or not, but here is why I won't be switching from rails to java anytime soon. I previously worked with c# and asp.net which may be comparable to java in many regards. I currently work with rails. In my experience, the ability to build rapid prototypes with rails simply trumps marginal gain you might get out of performance improvement with .net or java frameworks. I think the writer also agrees with this statement. Pretty much anything you build with java, you can build faster with ruby on rails. So I'll probably stick with rails for a while. Things might certainly be different for larger firms that have exhaustive developer resources to close the gap of developing time between java and ruby.
