Most Linux users cannot afford the amount of resource large enterprises like Google put into custom Linux performance tuning… For Google of course, there’s an economy of scale that makes all that effort worth it. A micro-benchmark suite, LEBench was then built around tee system calls responsible for most of the time spent in the kernel.
