年轻代老年代比例默认为3:8???

• https://docs.oracle.com/javase/8/docs/technotes/guides/vm/gctuning/sizing.html
  • For example, setting -XX:NewRatio=3 means that the ratio between the young and tenured generation is 1:3. In other words, the combined size of the eden and survivor spaces will be one-fourth of the total heap size.
• https://docs.oracle.com/javase/8/docs/technotes/tools/unix/java.html
  • Sets the ratio between young and old generation sizes. By default, this option is set to 2.

• ps
  • For example, -XX:SurvivorRatio=6 sets the ratio between eden and a survivor space to 1:6. In other words, each survivor space will be one-sixth the size of eden, and thus one-eighth the size of the young generation (not one-seventh, because there are two survivor spaces).
  • Sets the ratio between eden space size and survivor space size. By default, this option is set to 8.
