Tuning Concurrent Mark Sweep (CMS)
CMS is a generational low-pause collector recommended for JDK 7 and older versions. For JDK 8 and onward, we recommend using the G1 collector for applications that need low application pause times.
NOTE: CMS was deprecated in JDK 11 and removed from JDK 14. See JEP 363: Remove the Concurrent Mark Sweep (CMS) Garbage Collector for more information.
