Note: since Alex is a fairly gender neutral name I'm going to use they/them pronouns.

I went through and read it, and the submitter is incredibly confrontational and not at all open to feedback on the correctness of their benchmark. Also, when presented with contradictory evidence (their own benchmark where the results show io_uring is faster than epoll on other machines), they essentially dismiss it and says the other users ran their benchmark wrong, or that they can't reproduce their results on their machine, or that the other users used Boost and therefore are invalid. So not an entirely reliable criticism coming from them, in my opinion.
