--- Comment #49 from Alan Somers <asomers@FreeBSD.org> ---
(In reply to Gleb Smirnoff from comment #48)
But ZFS also doesn't use the page cache.  Maybe the problem is specific to =
file
systems that use the page cache and also run sendfile synchronously?

Do you use any torture test program with sendfile?  It looks like neither f=
sx
nor fio support it.
