Hi Json, I ran ebizzy and kernbench benchmarks on your 3.11-rc1 + your "V1 patch" on a 1 socket, 16 core powerpc machine. I thought I would let you know the results before I try your V2.
Ebizzy: 30 seconds run. The table below shows the improvement in the number of records completed. I have not spent enough time on the patch to explain such a big improvement. Number_of_threads %improvement_with_patch 4 41.86% 8 9.8% 12 34.77% 16 28.37% While on kernbench there was no significant change in the observation. I will try patch V2 and let you know the results.
