I did some informal measurements the other day running natively but 
calling the prestarted jobs, not running in thread.

For a "return todays date" program we have around 7ms, and for a full 
fledged Cobol component needing to open files and other stuff but not 
doing any work we have around 40 ms.      I _believe_ I have had smaller 
turn around times for repeated program calls from my PC.  These are 
measured from the Java program.

Our development machine is set to automatically adjust to workloads, and 
is as far as I know not tuned in any way for this.

We have been looking on this to get an idea of expected web service 
response times.
