Is the author right on this: http://www.linuxworld.com/site-stories/2002/0416.mainframelinux-p7.html "Linux memory management assumes control of a machine and so grabs up free memory for use in I/O buffering. Having multiple Linux instances do this to independently buffer I/O to the same files resident on a shared mini-disk not only wastes memory, but dramatically increases the paging effort."
Or has this already been addressed for Linux on zSeries? Thanks Werner
