We have single processor machines we tried moving the site onto. These machines couldn't handle the load. We watched as the load climbed to 80... 90... And then I was distracted for a few minutes and someone told me the machine had crashed. I wasn't surprised -- it couldn't handle it.
As for 2.0.x... We make heavy use of NFS. We need file locking to work. So we can't use it.
Thanks for the advice though...
