Executing a Shell-Skript

Hi,

I am trying to execute a shell-script using Runtime.getRuntime.exec(), but it seems to be very slow.

Executing the Skript from console it takes nearly 100 milliseconds, using Runtime.getRuntime.exec() it takes 700 milliseconds.

What do I have to do to increase the speed or is there a faster way to execute a shell script?

Thanks for any help,
Hal

There's no reason why executing a script from Runtime.exec() should be slow. How are you measuring the times? Do the commands within the script run slower, or is it slower to start up? What does the script do?

To measur the time in the console I am using the command time, which prints the used time in milliseconds.
In Java I subtract two Dates:


The script is a driver for a webservice, it sends requests to a service an prints the response.
