Hi, Ingo,
Part of the regression has been recovered in v4.7-rc1 from -32.9% to

Huang, Ying

Hi, Ingo,
Part of the regression has been recovered in v4.7-rc1 from -32.9% to
-9.8%. But there is still some regression. Is it possible for fully
restore it?
Details are as below.
Best Regards,
Huang, Ying
