The Performance Cost To SELinux On Fedora 31

Only with the timed GCC compilation did we see SELinux affecting the code compilation speed but compiling the likes of LLVM and the Linux kernel yielded no real difference.

When taking the geometric mean of 82 tests ran in this Fedora 31 SELinux comparison, disabling SELinux boosted the performance by about 5%. See all of the benchmarks in full over on OpenBenchmarking.org.
