The Limits of Copy-on-write: How Ruby Allocates Memory
02-Sep-2017 2687
Anyone who’s run Unicorn (or Puma, or Einhorn) may have noticed a curious phenomena. Worker processes that have been forked from a master start with low memory usage, but before too long will bloat to a similar size as their parent. In a big production installation, each worker can be 100s of MBs or more, and before long memory is far and away the most constrained resource on servers. CPUs sit idle.
