Mmm a feature, but always enabled?
Perhaps I can stop lvs from using it, by modifying the source?
The documentation (old) says that lvs loading is quite low so I wanted to test
it. At the moment I can't even do that in this case.
When I was asking about alternatives I was wondering If other loadbalancing
systems apart from lvs were available for Linux.

Mmm proportional fonts this end maybe
I'l cut and paste from vi:

That's a pity.
