I am not able to reproduce this issue. However I am trying to repro on a VM with 4 vcpus and 4 GiB memory and I don't see any difference. I am suspecting that it may repro on a larger machine but I don't have access to one. Can you please re-run this on your machine and run "perf record -a -g" in parallel while the actual test is running. thanks, Shakeel
