#Overview drip is an awesome command line tool that can be used to dramatically lower perceived JVM startup time. It does this by preloading an entirely new JVM process\instance and allowing you to simply use the preloaded environment. This has extraordinary results with jruby.

We reduced time to run rake environment from 13 seconds to a mere 3.5 seconds. This is actually at or near MRI 1.9.3p327 (with falcon patch) speeds!

Adding a few addition jruby options will reduce startup time even further (down to 1.69 seconds).

#Install Drip Install drip if you haven't already (see https://github.com/flatland/drip)
