My point was that unpatched 8.0.1 seems to have a pretty level TPM
rate.  If the patched version levels out at something not far below
that, I'll be satisfied.  If it continues to degrade then I won't be
satisfied ... but the test stops short of telling what will happen.
If you could run it for 2 hours then we'd probably know enough.
