Summary: "Overall most of our benchmarks this week of the new Linux

Kernel Page Table Isolation (KPTI) patches coming as a result of the

Meltdown vulnerability have showed minimal impact overall on system

performance. The exceptions have obviously been with workloads having

high kernel interactions like demanding I/O cases and in terms of

real-world impact, databases. But when testing VMs there's been some

minor impact more broadly than bare metal testing and also Wine

performance has been impacted. The latest having been benchmarked is

seeing if the Docker performance has been impacted by the KPTI patches

to see if it's any significant impact since overall the patched system

overhead certainly isn't anything close to how it was initially hyped by

some other media outlets."
