![]() ![]() We can spot the classic generational nature of the CMS GC in the heap configuration. When DataStage id a 32-bit application the maximum heap size is limited and it usually varies between 1.4 Gb and 1.8 Gb in Windows platforms and 2Gb and 3Gb for other Operating Systems. Metaspace used 423107K, capacity 439976K, committed 440416K, reserved 1429504KĬlass space used 55889K, capacity 62488K, committed 62616K, reserved 1048576K The first line reports the current heap size as 202 MB (206848 K) also, 42 MB (43061 K) is being used. As of this writing, Intellij IDEA is still using the CMS GC with the following heap info: par new generation total 613440K, used 114299KĬoncurrent mark-sweep generation total 1415616K, used 213479K Metaspace used 21031K, capacity 21241K, committed 21504K, reserved 22528KĪs shown above, we're using 28 MB of the heap and around 20 MB of metaspace. 1 Answer Sorted by: 0 This really depends on each application, since you can run java from the standard JDK/JRE, or there are different tools which generate. Maximum Garbage Collection Pause Time: The maximum pause time goal is specified with the command-line option -XX:MaxGCPauseMillis.For instance, if we run the same Quarkus app with ZGC via â-XX:+UnlockExperimentalVMOptions -XX:+UseZGCâ: ZHeap used 28M, capacity 200M, max capacity 1024M You can specify maximum garbage collection pause time, throughput, and footprint (heap size). This output may change depending on the GC algorithm.
