I think the networking stack in macOS is just not nearly as good as on Linux. I think it's fine for a small number of maxed out sockets, but the test that broke it was on another level. Actually, I think it was more than 25MB/sec, it was more like 55MB/sec, total, from 100's of peers. Honestly, until I got the 10G fiber, I never really tested macOS like this. I have no local tests which could generate that sort of throughput.
