Phoronix: More Windows Server vs. Linux Benchmark Tests With Spectre/Meltdown Mitigations

Last week I posted an article looking at the Relative Spectre/Meltdown Mitigation Costs On Windows vs. Linux. Today from a different system and using Windows Server 2016 rather than Windows 10 are some fresh benchmarks doing a similar comparison with different hardware and also looking at the Spectre and Meltdown mitigation performance impact again on Ubuntu 18.04 LTS and Clear Linux...
