Linux always all
In top, my java processes all show an average VIRT size of about 250MB
and an average RES size of about 150MB. Most of them were started with a
64MB heap size. I have two questions:
1. Top shows 0k of swap usage, so the system is not swapping. In that
case, why is there a difference between the VI
