If you have 50,000 servers for your service, and you can reduce that by 1 percent, you save 50 servers. Multiply that by maybe $8k per server and you have saved $400k,you just paid for your self for a year. With meta the numbers are probably a bit bigger.
LOL (I used to work for Meta, so appreciate the facetious understatement)
That's not how it works though. Budgets are annual. A 1% savings of cpu cycles doesn't show up anywhere, it's a rounding error. They don't have a guy that pulls the servers and sells them ahead of the projection. You bought them for 5 years and they're staying. 5 years from now, that 1% got eaten up by other shit.
yes, but latency-optimized schedulers tend to have _worse_ throughput, not better.
