I can reproduce the failure on mantic with both the DKMS and LRM

We are still looking into this issue. While we can reproduce the test
case and see difference in the performance, the delta is not as
significant and our results have not very consistent. I'm taking the
approach of setting up a more comprehensive test environment to run more
