The G1 full name is garbage the garbage Collector, which uses G1 to simplify the complexities of performance tuning. For example, the primary input parameters for G1 are initialization and maximum Java heap size, and maximum GC interrupt time. The G1 GC is made up of young generation and old generation.

G1 garbage collector (G1 GC) is a new Garbage Collector introduced by Java HotSpot VM in JDK 7, java SE 6 Update 14 already contains a G1 version (according to BKJIA's previous report, when Java SE 6 u14 debuted in early June, Sun's original statement was: the G1 Garbage Collector must be charged for use. Shortly after

The G1 garbage collector (G1 GC) is the newly introduced garbage collector for the Java HotSpot VM in JDK 7, and the Java SE 6 Update 14 already contains a G1 experience version (according to 51CTO earlier, when the Java SE 6 U14 debut in early June, the original Su The statement of N is: the G1 garbage collector needs

Refer to http://www.oracle.com/technetwork/tutorials/tutorials-1876574.html for detail. Some of the content is copied here. The G1 garbage CollectorThe Garbage-first (G1) collector is a server-style garbage collector, targeted for multi-processor machines with large mem Ories. It meets Garbage collection (GC) Pause time goals with a high probability, while achieving high throughput. The

also occurs in 3.OLD (young GC), where a Major GC is accompanied by at least one young GC, typically 10 times times slower than the young GC. The JVM does not have memory in the old area and will perform full GC. Old area uses the Concurrent-mark–sweep policy generally to reclaim memory. Summary: The Java garbage collector is a "self-adaptive, generational, stop-copy, tag-sweep" garbage collector. Disadvantages: STW (Stop-the-world) occurs during GC, and STW is time consumin

Powered by its unique design, the new concept was introduced to design electric vehicles, which shocked the world and brought the stormy electric vehicle industry back to life.

Oracle proposes to use G1 as the default Garbage Collector for Java 9 Oracle is considering including JEP 248 in Java 9's JEP list, that is, using G1 as the default Garbage Collector in server configuration.

greater than 4GB, you'll probably want to use the last algorithm-the G1 Collector.4. The G1 CollectorThe garbage First collector (G1) introduced in JDK 7 update 4 is designed to better support heaps larger than 4GB. The G1 collector utilizes multiple background threads to scan through the heap that it divides into reg

To solve this problem, CMS provides a switch parameter for the CMS to open the full GC when the memory fragmentation of the consolidation process, the process of memory collation can not be concurrent, space debris is gone, but the paus

Therefore,Parameter continuity is an over-limit on the smooth connection of parameter curves and is imposed manually.Parameter continuity is related to parameter selection and specific parameterization.
