I am talking about actual concrete solutions. “Do this code change and the bottleneck will go away”.
This person offered ACTUAL CONCRETE SOLUTIONS to performance issues. He literally opened bug-tickets and discussed with the team, and provided proof-of-concepts, but a FAANG manager attempted to shut him down.
This is not some snake oil salesman offering magic performance beans, this is someone who actually knew what they were talking about, and was able to diagnose performance problems in the operating system and solve it, for free. This isn’t some hypothetical, he REALLY did fix it despite being told it was impossible.
EDIT: Like the sibling poster said, the systemic solution is to "git gut". Which is clearly impossible as long as developers and managers foster a culture of dismissing performance, or in some cases inventing excuses not to work on it, as was seen in the Casey/Microsoft debacle.
