So I tested this on !THP too and the combined numbers are now:
|
[ SPECjbb multi-4x8 ] |
[ tx/sec ] v3.7 | numa/core-v16
[ higher is better ] ----- | -------------
|
+THP: 639k | 655k +2.5%
-THP: 510k | 517k +1.3%
So it's not a regression anymore, regardless of whether THP is
enabled or disabled.
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.
