CodePudding user response:

There are a lot of logic, one when the size of the object is greater than the young generation

CodePudding user response:

This just upstairs to say - XX: PretenureSizeThreshold parameters on the one hand, but if the young generation set is large, this parameter is useless, and if you have this object is just a method of local objects, also won't throw into old age, a word into the old age is a very complex process of judgment, the JVM will consider many because, in addition will also and you set the GC, as now the G1 designer judgment more complicated,
