Hello List, i have a few postgresql servers running in a Xen3/DomU and i am having real bead performance... Since read-ahead seems to be a big tuning detail, i would like to know where i have to set my read-ahead size? Do i have to set it in the Dom0 or DomU? My layers looks like this: 1.) Hard Disk (Dom0) 2.) LVM Partitions (Dom0) 3.) sda disk with ext3 (DomU) Or does someone have some experience with Xen and Postgresql?
