Well, it depends a lot on your mix of jobs. One other serious problem
is having code and anon pages evicted for files -- capping the files
at 5% or 10% can be a big help, too (and mostly corresponds with what
the world used to be like before UVM).

In general, the fact that UVM does not self tune is a serious lose.
