Also you must be careful adding storage you may not need because, depending on what OS you are using, the RSM algorithms for determining the 'least recently used' pages can take more CPU if you have more real storage to search.

In many cases you can increase buffers and get better performance. Theoretically more storage means more CPU cycles, but I strongly believe it won't be tangible. More RAM doesn't necessarily mean more AUX (page datasets). <joke> Or power down the z9, remove the book, remove some DIMM chips and put it in your child's PC - games need a lot of RAM </joke> -- Radoslaw Skorupka Lodz, Poland -- BRE Bank SA ul.
