      Description

        We added peak counts to NMT with JDK-8297958. That feature is *extremely* useful in analyzing native memory footprints since it gives you a glance into the past. For instance, it makes libc memory retention easier to explain.

        Originally, I restricted this feature to debug JVMs out of vague concerns about performance when running with NMT. However, after measuring, it turns out that the increase in cost is very small. Payoff in usefulness is huge, so I think it makes sense to have this feature always enabled. I also don't think we need a new switch for that.
