#!/bin/env groovy
println “hey”

my computer has a core 2 duo u9400 1.4 ghz cpu, 1 gb ram, win xp sp3, java 1.6.0_13, and groovy 1.6.3.

when i call it directly from the bash prompt it takes 10 seconds to run. when i call it as an argument to groovy.bat, it takes 7 seconds.

on the other hand, ruby ran it in less than 1 second and jruby ran it in 5 seconds.

groovy’s 7-10 seconds performance is very slow and a big turn off compared to using other dynamic languages. my sense is that groovy’s start time is the problem.

does anyone have ideas on how to make groovy run shell scripts faster?

I've played with Scala some and I believe that it will be about as popular as Groovy in 2 years or so. BTW, you ever use Jython? That a good suggestion for all of us.

IMHO a must for any groovy script that is intended for invocation from the command line.
