Ehh... if you want proof for a specific claim then ask for it. I am asking you for proof of the specific positive claim you made, which is:
> Solaris regularly beats Linux in performance on the same hardware, and the subsystems which are "slower" aren't really: they just don't lie and trade safety for performance, like Linux does. Linux is fake performance at the cost of correctness of operation.
The claims I did make is that in my experience Solaris had to be tuned to be reasonably performant. One example where tuning was needed by default was malloc. The default malloc from Solaris had horrible multi threaded performance . IIRC ZFS also had quite horrible performance by default if not tuned and I recall there were multiple tuning we had to do on new installations specifically relating to mmap to somewhat mitigate the poor integration of ZFS ARC cache and page cache which are documented here: https://github.com/openzfs/zfs/issues/225 and https://lists.freebsd.org/pipermail/freebsd-hackers/2016-Jul... there was also a whole wiki on ZFS tuning for various applications including MySQL.
