Years ago Alexandrescu said that Facebook estimated a .1% speedup to HHVM would save them $100k/year. It's presumably only gone up since then, but he's stopped giving an actual number in talks.
- ForOldHack 5y agoI would argue that he is bragging, and that the amount of code optimization is minimal. Large companies love to brag about how many servers they have, and optimizing compilation is just a buzz word. Go ahead, buy another servers. $100k is nothing. Its less than 1 engineer year vs 24,000 engineer years. The Distribution collectors, they brag about speed, and optimization is very important to them. They want to be able to test changes very quickly.
