Ruby is slow? She's fast enough for you.

V8 convinced me it's not quite impossible to optimize such a highly dynamic language. JRuby on JVM 1.7 could be decent once everyone has a lot of experience with invokedynamic. But most have found MRI is nearly as slow as Zend (PHP), and we picked up 6x performance by migrating our critical stuff from there to Java (we have enough machines to easily make that worthwhile).<p>I've already found Ruby nice for stuff we're confident we don't have a reason to scale, though.

No sir, Ruby is dead slow for my needs. For the things we work on, it can be used for some scripts here and there but that's it.

I love it when people try to tell me that a language is good enough for my needs without knowing what my needs are.

I'm really disappointed to see how many HN readers skim the first few lines of an article like this, and then comment as the informed reader.

No speed for you!
