We first tested again and confirmed the regression still exists (-21.4%), the result is stable [1], more details are in [2].

Then we tried another platform, Ice Lake, it has 128 threads 2 sockets Intel(R) Xeon(R) Gold 6338 CPU @ 2.00GHz with 256G, but we found the regression is still existing (-5.4%), the result is stable [3], more details are in [4].
