Ruby 2.1 Garbage Collection: ready for production
Sam Saffron Programming, Techno logy and the Art of Hacking The article â€œRuby Garbage Collection: Still Not Ready for Productionâ€ has been making the rounds. In it we learned that our GC algorithm is flawed and were prescribed some rather drastic and dangerous workarounds. At the core it had one big demonstration: Run this on Ruby 2.1.1 and you will be out of memory soon: while true "a" * (1024 **

Garbage collector tuning in Ruby 2.0
There's a fair bit of confusion about these GC tuning parameters. REE (which is a fork of Ruby 1.8.7) introduced its own parameters first, and later Ruby (starting in 1.9.2) introduced its own (similar) parameters. Ruby 1.9.3 made them customizable via environment variables, and Ruby 2.1.0 added a lot more. This blog post goes into great detail about garbage collection in MRI and what all the tuni

Ruby 2.1: Out-of-Band GC Â· computer talk by @tmm1
29 Jan 2014 Ruby 2.1's GC is better than ever, but ruby still uses a stop-the-world GC implementation. This means collections triggered during request processing will add latency to your response time. One way to mitigate this is by running GC in-between requests, i.e. "Out-of-Band". OOBGC is a popular technique, first introduced by Unicorn and later integrated into Passenger. Traditionally, these
