Much of my testing was on Linux 4.14.11 Some older kernels have the KAISER patches for Meltdown, and so far the performance overheads look similar. Also microbenchmarks, which often stress-test the system, will suffer the largest losses. virtual (bgregg-c5.9xl-i-xxx) 02/09/2018 _x86_64_ (36 CPU) 05:24:51 PM proc/s cswch/s.
