AMD Zen 5 Not Affected By Inception/SRSO, mitigations=off Yields No Benefit On Ryzen 9000 Series
With Hackbench that historically has shown quite a difference from CPU security mitigations the overall impact was very small in that synthetic scheduler workload.
Database workloads were impacted a lot from earlier CPU security mitigations but didn't make much of a deal with Zen 5 when running with mitigations disabled.
Rather oddly, all of the Apache IoTDB benchmarks were running faster in the default (security mitigations enabled) mode compared to when running mitigations=off.
