JVM principle and Performance Tuning series (JVM tuning)

The individual believes that JVM tuning is primarily addressed by the following methods

1. Set the appropriate maximum heap memory (maximum and value for Cenozoic and Laosheng generations) and minimum heap memory (the operating system memory size consumed by JVM startup), and set the scale allocation of the heap.

2, set up the suitable new generation because of its impact on the system performance and GC recovery has a certain effect.

3. Set the appropriate persistence generation because it directly determines how many class definitions the system can support and how many of them are normally lit.

4. Set the appropriate thread stack otherwise the system may exit abnormally due to insufficient resources and space required by the thread.
