Caching and a whole lot of it. Most of their pages could be served by a CDN.
How much do you think stack overflow is reading vs writing? How often do you even click a link from a stack overflow page once there?
- quickthrower2 8y agoUpvotes are clicked a lot but I guess they are just an api call and can be tuned to be high performance.
- luckydata 8y agoit's also not super critical to show correct numbers in real time for that so there's that.
- bradlys 8y agoI rarely click anything on stack overflow and neither do most people I know. The only ones I know who do that are stack overflow evangelists. I'd guess very few people have an account and use it.
- quickthrower2 8y agoI’m in between. I have an SO score of just 1000, but I vote a lot. Mainly because I’m logged in via oauth anyway so it’s no hassle to do so.
- guelo 8y agoI've taken to using upvotes for bookmarking, that way when I inevitably look the same question up again six months from now I'll know which of the answers I thought was most useful last time.
- why-el 8y agoUpvotes are actually ideal for an in-memory service like Redis that fsyncs less frequently. Even if you lose the last few reads (highly unlikely, with some care), it's not the end of the world.
