Re: Fast execution of scripts

But I want to be able to change the script and still have it start up 
nearly instantly. The default script runner doesn't do that no matter what 
arguments you pass to it. A solution like nailgun could be interesting if 
it worked with scala. Nailgun only cuts the start up time of the JVM. It 
doesn't reduce the compile time for the scala code.
It's true that my solution means that the code runs on the same JVM 
instance and the state of globally accessible objects stays the same 
between invcocations. And that can pose a problem. But starting up the a 
new JVM instance normally takes only a fraction of a second. And all the 
libraries being used are precompiled.
So I don't see why the script runner is not able to get the startup time 
down to a fraction of a second despite the use of a compile server. My 
example seems to show that a small script can indeed be compiled in less 
than 200 ms. Combine that with a JVM spin up time of another 200 ms and you 
should end up with 400 ms, not 2 seconds.
