RE: new PC specs

 Which would make sense in some cases.  I wonder if when I was having
problems more related to when I was working with the Websphere Testing
Environment and Java related tasks - and therefore nearly all
processing/compiling was being done on my machine.


Thanks for the correction John,
Aaron Bartell

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.
