GroovyServ made a start-up time of the invocation of Groovy script very quick. However, it can be used not only for Groovy but for all JVM languages, e.g. Scala, Jython and Clojure, etc.
On Linux, when setting the following aliases, You can enjoy the power of GroovyServ for Jython:
- alias gython="groovyclient -cp /tmp/jython.jar -e 'import org.python.util.jython; jython.main(args)' --"
- $ time jython -c "print('Hello')"
- Hello
- real 0m2.503s
- user 0m2.891s
- sys 0m0.431s
- $ time jython -c "print('Hello')"
- Hello
- real 0m2.613s
- user 0m2.889s
- sys 0m0.435s
- $ time gython -c "print('Hello')"
- Hello
- real 0m0.959s
- user 0m0.001s
- sys 0m0.003s
- $ time gython -c "print('Hello')"
- Hello
- real 0m1.156s
- user 0m0.001s
- sys 0m0.003s
Gython(Jython + GroovyServ) is faster by one second than normal Jython. In the above way, the overhead which groovyclient passes the classpath of the additional jython.jar to groovyserver at each invocation is so large. You can do it still faster by starting groovyserver with CLASSPATH environment variable which has jython.jar.
- $ alias gython="groovyclient -e 'import org.python.util.jython; jython.main(args)' --"
- $ export CLASSPATH=/tmp/jython.jar
- $ groovyserver -r
- $ time gython -c "print('Hello')"
- Hello
- real 0m0.909s
- user 0m0.001s
- sys 0m0.002s
- $ time gython -c "print('Hello')"
- Hello
- real 0m0.076s
- user 0m0.001s
- sys 0m0.003s
- $ time gython -c "print('Hello')"
- Hello
- real 0m0.045s
- user 0m0.001s
- sys 0m0.003s
Notice 1: I can't assure that a testing framework or a complex library works well. Do it by your self-responsibility ;-)
Notice 2: If your OS is Windows, use Groovy and GroovyServ which are installed from Zip archives. I experienced a trouble by using them of Windows-installer of version 1.8.0.
