Ruby Performance Best Practices
The Addison Wesley Professional Ruby Series just released a new shortcut on the somewhat contentious subject of Ruby performance entilted Writing Efficient Ruby Code written by the highly regarded Rails performance expert Dr. Stefan Kaes. So far (page 10), I’m impressed by the content. Most languages need (and some have) general best practices guides such as this. I found it particularly refreshing to see that the title of page 5 is:
Ruby’s Interpreter is Slow.
And that the next few paragraph that follow explain why from an interpreter point of view, which directly relates to the work being done by the JRuby team on the Java JVM, the Rubinius team with their new Ruby VM and Ruby 1.9/YARV.
