Keep in mind the "default" performance is what you are used to seeing from our prior Ryzen 5000 series benchmarks on phoronix and elsewhere with most testing in the default/out-of-the-box configuration.
As with previous CPU generations, disabling the mitigations via the "mitigations=off" control can help with the I/O performance but puts your system vulnerable to Spectre V1/V2/V4. In any case, the Ryzen 5 5600X performance continues to shine with great generational uplift regardless of mitigation state.
