    Is there any information on the performance impact of the microcode fix or is it too early for that?

      So far the word is the microcode fix causes negligible performance impact, but using the MSR fix causes 5-15% loss. In my own testing on EPYC hardware, microcode made no noticable difference to my workloads and benchmarks. Same as random noise in results.
