RE: Performance when using POI to create an excel workbook.

... I found the next best thing, his slide show to COMMON Europe last year:

http://common-es.info/files/RoadShow2005/JavaPerformance.pdf

In it, Blair says specifically (slide 23) that there are two modes:
java.compiler=jitc and java.compiler=jitc_de.  The second one is the "Direct
Execution" mode which requires CRTJVAPGM to be run on the JAR files; this is
generally slower than the other setting, which uses the JIT compiler, and
has been since V5R2.
