When booting, I have strange message.
All work OK (processor with hyperthreading, but system seems it as 1 CPU ).

Compatible mode usually gives slower response. Unless you need it, don't run it.
I have a P4 2.8GHz. Same thing happens.

WITNESS seems to be a common part of current, especially with 9.0.
