Memory profiling with JRuby

Ruby JRuby

Many of you have asked how to inspect a running JRuby instance’s
memory layout, so I finally wrote up a blog post on the tools I use
most often: jmap/jhat and VisualVM.

I hope you’ll all play with the tools and write up blog posts or wiki
articles on your experiences :slight_smile:

Also saw this the other day:

A slightly ruby-ified version I suppose.
