That's a good first rule. My second rule of thumb would be put test and production Linux guests on different VM systems, perferably far apart :) Those test pesky test guests can cause you all kinds of headaches when they go looping or eating up all their storage and dumping :)

Hi, Lionel. My first rule of thumb for z/VM performance is to install and use a good performance monitoring tool. ;-)If you are using Velocity's products, there are some good performance hints and tips that you can grab off of their web site, I believe. Rob van der Heij of Velocity gave a very good performance session at the recent z/Expo over in Europe that shows how he solved three z/VM performance problems in detail. I can send you a copy of the presentation, if you'd like. IBM has done a good job over the years collecting and making available all of the raw performance data needed to be able to quickly and accurately determine what is causing performance problems and how to fix them. Have a good one. Lionel B. Dyck wrote: > Is there a published set of rules of thumb for z/vm performance?
