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?
Thanks,
Mario
