What exactly is “OS performance”, if not running applications? Micro benchmarks can be compared to premature optimization. Which we all know is the root of all evil.
There are lots of realistic workloads where some benchmark gives completely opposite and counter intuitive results, often due to caching and scheduling tricks.
- sedatk 5y agoI thought I already explained this. OS isn't the sole, maybe not even the main arbiter of performance when compiler and developer biases can cause a greater difference. I already explained that some scenarios (like FS) would have significant variance due to the differences in design philosophies. That doesn't have to mean that one OS is objectively worse than the other, but it could mean that they prioritize different scenarios. I don't think we have any way to tell if an OS is objectively "faster" without resorting to micro benchmarks which you're right about them not being so meaningful.
