Tuning |
Each JVM was placed in the FX priority class with the priocntl command. Each JVM was run in its own processor set containing one core. Tuning added to /etc/system set autoup=345600 set tune_t_fsflushr=345600 set segmap_percent=1 Sun System Firmware patch 127580-01. |
Notes |
This result was measured on the Sun SPARC Enterprise T5220 The Sun SPARC Enterprise T5220 and Sun SPARC Enterprise T5120 are electronically equivalent. |
