Hi all, > I wonder if any performance impacts on lustre with the new security > patches for the Intel?
According to our initial tests on 3.10.0-693.11.6.el7.x86_64 kernel (Centos 7.4) with Lustre 2.10.2, there is a penalty of ca. 10% in nice workloads (1MB IO) up to 40% in 4k IOs. Tested with IOR. It looks bad, however probably we don't need to patch the servers, as Lustre lives in kernelspace anyway. Some kind of advisory from Intel HPDD would be nice here.
