This has not been my experience in the field. If you use the Performance
Monitor in Windows, you can get a real time picture of what's going on while
WDSc is running. With the exception of initial program load, the disk is not
getting hit very hard -- at least not in a typical iSeries programming
environment (ie: RPGLE, CL editing). It's the processor that keeps getting
slammed.
