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. I've since tested the 4.4.115 kernel and confirmed that pcid is used there.
