--- Comment #12 from Jan Kara ---
4.18 vanilla kernel numbers:
Amean 1 27.80 ( 0.00%) 26.42 ( 4.99%) 26.98 (
2.94%) 25.19 ( 9.41%) 26.81 ( 3.56%)
Amean 2 31.14 ( 0.00%) 30.74 ( 1.30%) 34.20 (
-9.82%) 34.22 ( -9.88%) 31.36 ( -0.71%)
Amean 4 37.22 ( 0.00%) 41.98 ( -12.78%) 39.83 (
-7.01%) 33.91 ( 8.90%) 41.87 ( -12.49%)
Stddev 1 7.47 ( 0.00%) 6.63 ( 11.34%) 7.09 (
5.14%) 5.18 ( 30.62%) 6.73 ( 10.00%)
Stddev 2 8.42 ( 0.00%) 8.05 ( 4.43%) 8.13 (
3.49%) 8.46 ( -0.48%) 8.37 ( 0.53%)
Stddev 4 8.84 ( 0.00%) 6.54 ( 26.01%) 6.06 (
31.48%) 7.32 ( 17.27%) 6.94 ( 21.56%)
Better numbers overall but still unstable. I guess I'll check that
a) intel_idle.max_cstate=1 still fixes instability with 4.18
b) what is missing wrt scheduler / cpufreq in 4.18 compared to what we have in
Leap 15.0.
