Say the post had been "How Netflix uses FreeBSD to achieve network latencies less than 10 microseconds" or something. How helpful would it be to comment about how "for most people" this doesn't matter?

Did anybody who read the tweet think it mattered to them when it didn't? It mentions Firecracker explicitly. How many people on HN do you think upvote this because they themselves are running FreeBSD on Firecracker, versus the number who upvoted because it's just interesting in and of itself?

Maybe? Having worked in way too many teams that were convinced we had to aim at some crazy tech because someone else saw "50% increase in throughput" on some tech stack; I am happy to be the one saying to keep perspective.

Though, I will note that you picked a framing with absolute timing here. That is the root criticism here. If the headline would be "team saved 2ms off 28ms startup routine," it would still be neat and worth talking about. Would probably not have impressed as many folks, though. After all, if they save 1% off training time on a standard ML workload, that is way way bigger. Heck, .07% is probably more time.

I'm reminded of a fun discussion from a gamedev, I think it was Jonathan Blow, on how they thought they were smarter than the ID folks because they found that they were not using hashes on some asset storage. He mused that whether or not he was smarter was not at all relevant to that, as it just didn't matter. And you could even make some argument that not building the extra stuff to make sure the faster way worked was the wiser choice.

If we didn't have you here we might have done the terrible mistake of thinking this was interesting. I'm so glad you were here to show us how useless this effort is, protecting us from wasting our time, protecting us from our lack of judgment. Thank you so much for your service and foresight.
