Zombieload V2 TAA Performance Impact Benchmarks On Cascade Lake

The socket performance is lower with the new mitigation.

Cascade Lake's context switching performance up to now has been great. The context switching speed with Cascade Lake is a big improvement over the Skylake mitigated performance, etc. Unfortunately now with TAA, the context switching speed measured by ctx_clock is multiple times slower.

Memcached was seeing small but measurable differences from the TAA mitigation.

The Nginx and Apache web servers were also impacted by this latest security mitigation.

For those wondering the combined impact now of all the security mitigations on/off for Cascade Lake and other generations, additional follow-up tests will be coming soon.
