The current updated table of performance results is: ------------------------------------------------------------------------- [ seconds ] v3.7 AutoNUMA | numa/core-v16 [ vs. v3.7] [ lower is better ] ----- -------- | ------------- ----------- | numa01 340.3 192.3 | 139.4 +144.1% numa01_THREAD_ALLOC 425.1 135.1 | 121.1 +251.0% numa02 56.1 25.3 | 17.5 +220.5% | [ SPECjbb transactions/sec ] | [ higher is better ] | | SPECjbb 1x32 +THP 524k 507k | 638k +21.7% SPECjbb 1x32 !THP 395k | 512k +29.6% | ----------------------------------------------------------------------- | [ SPECjbb multi-4x8 ] | [ tx/sec ] v3.7 | numa/core-v16 [ higher is better ] ----- | ------------- | +THP: 639k | 655k +2.5% -THP: 510k | 517k +1.3% So I think I've addressed all regressions reported so far - if anyone can still see something odd, please let me know so I can reproduce and fix it ASAP. Next I'll work on making multi-JVM more of an improvement, and I'll also address any incoming regression reports.
