It was an example why results might be different.

It is not. The GC is interacting with low-level OS parts and can
be triggered any time during your benchmarks.
For similar results, you should run the benchmarks with
the same Mono version on the same hardware with a disabled
GC. It's not realistic, but so are micro benchmarks.
