let me address this separated ...

either your 6 servers do really hard work, which will
bring down every system sooner or later, or your kernel
and/or configuration is not optimal. Another reason
could be a slow I/O (disk) and/or memory interface,
which usual is the bottleneck nowadays ...

what you could do/try:

 - get a recent kernel and patch rmap and maybe O(1)
 - use faster memory/disks (maybe striping, raid5)
 - add a second processor, SMP systems are much more
   resposive (smooth) with vservers

I agree that this sounds interesting and it might be
a viable solution to scale the vserver project beyond
the physical limits of one MP machine ...

I do not have any deeper knowledge of OpenMosix and
no Farm where such a project could be tested/developed
so if there is interest in doing this, we'll need both.
