    Nginx: sendfile or aio on FreeBSD 13.1+ZFS?

    Greetings. Nginx states (Changes with nginx 1.21.5 - 28 Dec 2021): Change: now nginx always uses sendfile(SF_NODISKIO) on FreeBSD. So it seems, it uses "sendfile: on;" by the default on FreeBSD. Afaik, sendfile should be off for FreeBSD and ZFS, to avoid redundant data caching. I'm on ZFS...
