If you mean this site:

https://benchmarksgame-team.pages.debian.net/benchmarksgame/

then those comparisons are not that meaningful, given that each program
is written differently and with a different algorithm and using a
different compiler.

There are even multiple versions written in the same language, so what
is it comparing?

But do you see differences where you expect them to be, between for
example a program in native code, and one that is interpreted. But you
don't need that website for that.

And, yes, you would also expect contributions to that site to be highly
tuned to those tasks.
