Ask HN: How long does it take you to deploy?

And how often do you deploy? Would love to hear about different stacks, stages of product/company, how often you push to prod, and especially how long it takes from start to finish

I'll start- right now our large but fairly vanilla Rails app takes about 15 minutes: 5 minutes for tests on CI to pass, then 10 minutes for deploy (mostly because of asset compilation time).
