Hey, We experienced the performance issue on different hardware servers:
LENOVO System x3650 M5 Lenovo ThinkSystem SR650 with the following kernels: 4.15.0-137-generic: disk performance issue 4.15.0-139-generic: disk performance issue 4.15.0-140-generic: disk performance issue 4.15.0-142-generic: disk performance issue I haven't seen this issue on virtual machines (VMware VMs Ubuntu 18/20). At the moment, I'm testing "4.15.0-144-generic". To early to say it is free of the bug - I will come back in a week.
