Even without a specific max heap size, it might be desireable for a program to get hints about memory usage -- possibly, say, doing so if the GC has to start throttling other activity to keep up with the amount of GC it needs to do. I was going to also say that it'd be nice ...

VIRT:virtual memory usage 虚拟内存 1、进程“需要的”虚拟内存大小,包括进程使用的库、代码、数据等等。 2、假如进程申请100m的内存,但实际只使用了10m,那么它会增长100m,而不是实际的使用量 SHR:shared memory 共享内存 1、除了自身进程的共享内存,也包括其他进程的共享内存 ...
