--- Comment #8 from Sebastian Dröge (slomo) <slomo at coaxion.net> ---
We should get this fixed before 1.16 as it's a severe performance regression.


Alternatively we could also consider doing our own buffering inside filesink.
Collect buffers until a threshold is reached and then writev() them all in one
go, which is basically what fwrite() is doing internally.
