 |  +       #CGIT_CFLAGS += -DHAVE_LINUX_SENDFILE
 ...
 |and
 |
 |  make NO_LUA=y NO_ICONV=y NO_GETTEXT=y NO_TCLTK=y NO_PERL=1 \
 |    NO_PYTHON=1 NO_SVN_TESTS=y NO_REGEX=NeedsStartEnd prefix=/usr
 |
 |and .. it works.

 |Thank you, i will open an AlpineLinux bug report.  And lighttpd.

Did that.  Though redmine lighttpd threw me out after password
reset, i posted in #lighttpd irc.freenode.net a few minutes ago.
FreeBSD also has a sendfile by the way, had that already twenty
years ago, and worked great!  Slightly different semantics though.
But doable (by then).  The guys from nginx strive for tweaking the
last little thing out of that btw.  Just last week iirc they added
NUMA specific ioctls to be able to gain more locality.

I think i will go again soon, now that this is worked out :)
Thanks,
Ciao and greetings from Germany,
