In the openssl test, the machine appears around 6 times faster than
previously now. The performance numbers from openssl speed are
reasonable and expected now. I've triggered the regular CI workload now
and the performance looks much better.

I only used openssl here, because it was so readily available and
because it seemes remotely similar to the target workload. I'd have to
install something else. I didn't see a use to have a very precise
benchmark here, because it was fairly obvious that the performance
numbers were wrong by a magnitude.

Would you mind telling what changed about the machine? In any case, we
can mark the ticket as resolved and skip futher research.

Thank you
