AOT Compilation   Tuning /etc/system parameters: autoup=345600 tune_t_fsflushr=345600 The frequency of file system sync operations. disable_memscrub=1 Turn off the memscrubber daemon. lgrp_mem_pset_aware=1 default random policy applies only to lgroups with a process' processor set. Each JVM was run in its own processor set containing two cores (one whole chip). Each JVM was given 32 Mbyte pages with the ppgsz command. Each JVM was placed in the FX priority class with the priocntl command. Notes
