I have done longer testing of kernel 140 and it has performance degradation issue as well. It took a couple of days to fully max out disk IOs on that kernel with the same load. Therefore, I came back to testing the other kernels in longer time-window.
At the moment, I'm running kernel 4.15.0-137-generic. Will leave it running for the next few days to see if there is any difference.
