So why did Facebook build that whole system of converting C++ to PHP or whatever they did? Was it because they didn’t understand the savings? Or when you scale that high, the savings really are significant? Were there savings?
Edit to subtract: https://en.wikipedia.org/wiki/HHVM is what it eventually turned into, and apparently it showed significant improvements even above the previous system.
Probably because someone said it was a good idea in a meeting.
There is absolutely no way that’s true lol
Its the most true thing you'll read all day.
You should look into it. Apparently it was quite a performance increase. I don’t understand all the technical details, but it is very cool to see what large enterprises do at scale.
