sendfile(2) is used in the nginx measurement.

As for your Netflix question, I don’t have the answer for you.

Does is how dragonfly does it better or worse than FreeBSD?

Also, given your expertise – why do you think Netflix uses FreeBSD instead of dragonfly?

However, the VM page operation for the sendfile is running directly in the user context.

Speaking of Netflix and FreeBSD, how does FreeBSD async sendfile compare to Dragonfly?

Netflix collaborated with Nginx team to rework FreeBSD sendfile to make it way more performant.
