http://www.ibm.com/developerworks/linux/linux390/perf/tuning_how_fixed_io_buffers.html If you are on z/VM 5.1, the most obvious indication is high paging to expanded storage even though z/VM has plenty of free pages. When your Linux kernel is old too, you may not have that option. In that case some relief can be found in taking advantage of MDC. And obviously in making the virtual machine footprint smaller. http://www.vm.ibm.com/perf/tips/2gstorag.html Rob -- Rob van der Heij Velocity Software, Inc http://velocitysoftware.com/ ---------------------------------------------------------------------- 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
