Phoronix takes a look at the relative Spectre/Meltdown mitigation costs on Windows vs. Linux
A quote from the article:
The latest in our Windows versus Linux benchmarking is looking at the relative performance impact on both Linux and Windows of their Spectre and Meltdown mitigation techniques. This round of tests were done on Windows 10 Pro, Ubuntu 18.04 LTS, and Clear Linux when having an up-to-date system on each OS where there is Spectre/Meltdown protection and then repeating the same benchmarks after reverting/disabling the security functionality.A Look At The Relative Spectre/Meltdown Mitigation Costs On Windows vs. Linux
This round of tests were done on an Intel Core i7 8700K "Coffee Lake" system used throughout the entire benchmarking process and all BIOS/system settings remained the same during the testing process.
