Intel Core i5 8400 vs. i5 9400F Meltdown/Spectre/L1TF/MDS Mitigation Impact

The Stress-NG kernel micro-benchmarks show the Core i5 9400F often coming out slightly faster as we would expect but with generally similar hits to the performance as a result of these default/out-of-the-box mitigations.

The time to perform a context switch on these Coffeelake CPUs is still nearly 6.5x higher as a result of these mitigations.
