Good afternoon, We have recently started executing performance testing on the new rhel 8.10 lustre kernel. We have noticed an drop in performance in our initial testing. Its roughly a 30-40% drop in total IO observed with our FIO testing. My question is has anyone else noticed any performance decreases? Hi Rashun, could you please be more specific about what you are comparing? Which version of Lustre for the old and new kernel, and was it the same before upgrading to RHEL8.10? Which RHEL version are you comparing against, RHEL 8.9? Have you upgraded both the clients and servers to RHEL8.10, or only the clients?
