As measured by what? CPU values gathered within a guest are pretty much a meaningless number other than proportional use of resources within a timeslice. The number of runnable processes shown by 'uptime' is a smoothed average of the number of potentially runnable processes over a 5 min period. All that tells you is whether you have enough CPU to service the demand you're imposing; if that number goes way up, then you're asking for more than the resources you have can deliver and you're waiting for resources (only way to fix that is: a) fix the application to not ask for excessive amounts of resources, b) give the machine more resources). What are they using to measure load? ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 ---------------------------------------------------------------------- For more information on Linux on System z, visit http://wiki.linuxvm.org/
