Your numbers are quite different from my previous benchmark with UP under
2.2.18. While your system time does not increase much, mine did. On the other
hand, your user time increased significantly, while mine did not. Also, the
slowdown is higher in your environment than in mine, despite some optimizations
in v1.1.1.

How many runs did you do? Because of these variations I would like to see at
least 3 runs in single user to be sure. Do you still have your setup, and if
yes, could you possibly make some more runs each?
