current mono default garbage collector

Question

What is the current GC implementation in mono 4.2?

• According to http://www.mono-project.com/docs/about-mono/releases/3.2.0/:

  Mono now defaults to the SGen Garbage Collector.

• According to http://www.mono-project.com/docs/about-mono/releases/4.4.0/ (preview changelog):

  The libmono library now defaults to using Mono with SGen, previously, it defaulted to Boehm.

Thanks in advance for clearing this up.

Answer 1

SGen is the default collector.

Mono's Cooperative Mode for SGen GC

As of today, Mono's Coop engine can either be compiled in by default (by passing --with-cooperative-gc to configure), or by setting the MONO_ENABLE_COOP environment variable to any value.

We have used a precursor of Coop for about 18 months, and now we have a fully productized version of it on Mono master and we are looking for developers to try it out.

We are hoping to enable this by default next year. 1 Astute readers will notice that it still took years of development to make SGen the default collector in Mono.
