LOL, no. That's bisecting the patches to find the spurious latency jitter in the critical path, that's, carefully planning apps to fit the specific NUMA design, being on the first name basis from the engineering of NIC vendor, etc, etc.

I've been SRE too and the most it brought to the table is a concept of error budget.

I can only agree that "billions of dollars" in trades is not much.
