The Stress-NG kernel micro-benchmarks obviously are able to show a significant difference in the speed of various operations as a result of the MDS mitigations.

The very basic ctx-clock program is also able to show how much longer context switches are taking as a result of the Microarchitectural Data Sampling mitigations. Most significantly affected was the latest-generation Core i9 9900K.

Memcached is another real-world workload impaired by MDS.
