Lessons learned today:
- Your theoretical expectation on something is very prone to error and do not believe it even when you are very sure. Prove it by data.
- Do not measure the outcome of multiple changes at once.
- Do not create an account with a very simple password on a publicly available computer, someone will log into it and eat your CPUs.

So I measured one change (the SLUB numa locality change) at a time and the data seems to be nice I think? (at least on my old Broadwell machine with 2 sockets)
The "Neither a win nor a loss" situation was because one change was a win and the other change was a loss.
But it's still synthetic hackbench and I wonder how it would perform on network benchmarks - but not sure if I could benchmark this enough on local env cuz I only have 2.5Gbps lan cards.
