tunable is usually set to 10000ms by the operating system. The default is
changed by numad to be 1000ms since it is helpful for the hugepage daemon to be
more aggressive when memory moves between nodes. Specifying (\fI\-H 0\fP) will
cause numad to retain the system default value. You can also make the hugepage
daemon more or less aggressive by specifying an alternate value with this
option. For example, setting this value to 100ms (\fI\-H 100\fP) might improve
