Performance impact of x86 / intel CPU issues once PTI enabled on network hardware.

I expect a lot of you have heard about this fun little issue which now has a logo and webpage - http://ift.tt/2EOJNax

I'm interested in how the mitigation being put in place of page table isolation (PTI) is going to impact our network workloads - especially for those of us using NFV and virtual networking and firewalling. Could be enough of a performance hit to require some significant rework in the case of packet filtering and load balancing. Anyone aware of decent network benchmarks post PTI?
