Are there any studies, white papers, redbooks, presentations, articles, or ... that address how to use WLM to effectively improve the performance of long running shell scripts invoked via (a) TSO OMVS, (b) Batch job, or (c) ssh? With the script spawning several address spaces this can be a challenge.
Can you give any more details on the performance problem? I did some testing of a script few years ago which generated around 5000 address spaces per minute. Depending on what you are doing that might be considered fast or slow... but if it's too slow, maybe another language would be a better choice.
One thing I found was that bash was very slow for scripts compared to /bin/sh - it used more than 10x the CPU time.
