>Description:
After updating to version 2.2.2, Netatalk uses sendfile to transmit data to the client. As documented in kern/141305, this causes severe performance issues for Netatalk shares hosted on ZFS volumes, manifesting itself in extremely low network transfer speed, while causing excessive disk I/O.

Please consider exposing the --disable-sendfile configure switch introduced in Netatalk 2.2.2 through the port's config options.
>How-To-Repeat:
- create Netatalk share on ZFS
- read any files from the share
- watch transfer rate and server-side disk I/O
>Fix:
Create a config option for disabling the use of sendfile. Patch attached.
