Benchmarking The Performance Overhead To The Linux Kernel Runtime Guard

Out of 90 benchmarks run comparing the performance hit on this Intel Core i9 9900KS from LKRG, having LKRG enabled led to around a 5% hit based on the geometric mean of all tests carried out. Granted, some real-world workloads like code compilation speed were impacted much more dramatically while test cases not involving I/O or other kernel operations tended to see no measurable difference in run-time performance.
