Recently I made a bunch of various benchmarks to test Unity's Burst compiler against native compilers. I've also included Mono and CoreCLR out of curiosity, the code is available here in .NET folder. I've noticed strange results in two tests (Sieve of Eratosthenes and Particle Kinematics) where CoreCLR performs way much slower than Mono for some reason, I think this requires in-depth analysis by appropriate developers of .NET Core.

I'm happy to provide any additional info or assistance if required.
