Concurrent mark sweep collector

The Concurrent mark sweep collector (concurrent mark-sweep collector, concurrent collector or CMS)[1] is a mark-sweep garbage collector in the Oracle HotSpot Java virtual machine (JVM) available since version 1.4.1.

HotSpot garbage collectors
Main article: HotSpot

The HotSpot JVM selects the default garbage collector based on several factors.[2] The newer Garbage-first collector (G1) is planned to replace CMS.[3]

To launch the JVM with this garbage collector you can add this property to the java command line -XX:+UseConcMarkSweepGC [4][1]

gollark: You can't just make programs arbitrarily small and so not require documentation.
gollark: As if I wrote a *manual*.
gollark: I agree. I simply remember how my code is structured, and everyone else can just reverse engineer it.
gollark: <@135522209899741184> Maybe GNU Radio would work well for you?
gollark: And people complain about Intel WiFi stuff, although I've never actually had any issues with it.
