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

Parallel worlds of CRuby's GC
The document discusses parallelizing garbage collection (GC) in CRuby. It describes the current single-threaded GC approach and argues for a parallel marking GC to utilize multiple CPU cores. Key points covered include explaining GC concepts like dead objects and roots, an overview of CRuby's mark-and-sweep algorithm, and the motivation to parallelize marking to improve performance.
