we reported regression on a 2-node Skylake server. so I found a 1-node Skylake
desktop (we don't have 1 node server) to check.
model: Skylake
nr_node: 1
nr_cpu: 36
memory: 32G
brand: Intel(R) Core(TM) i9-9980XE CPU @ 3.00GHz
but cannot reproduce this regression:

for

the regression is smaller but still exists.
