I've been looking at Linux tuning params and see some configs where SACK is turned off. Can anyone explain this?
This would be tuning for a busy web server.
I have a machine running 8.04 LTS that I would like to migrate to using Xen. There seems to be a dearth of information on how to do this without having to wipe the entire machine.
I do have another machine available to host things on if that helps. So the current state is
server001 server002
I would like to get to
server001
- virtual server001
- virtual server002
Leaving me free to decommission the physical server002.
