The performance benchmarks of IO.JS vs Node.js can be found over here.
IO.JS is recommended if you are working on a new project, if you are using a project built on Node.js, it has a few bugs or might not support IO.JS due to several reasons.
You can download IO.JS from here
Double click the pkg.
Go through the setup.
If you prefer installing IO.JS using Homebrew, you can do that by running (Homebrew is required).
brew install iojs
brew link iojs –force
Open Terminal and check the IO.JS and NPM version.
