Jukka Zitting commented on JCR-3735:
------------------------------------
bq. This step is an additional overhead when the upload process itself creates
a temporary file.
IMHO the additional overhead is the temporary file created by the upload
process before passing the incoming stream to the DataStore.
bq. use the FileChannel object associated with the input stream to copy the file
We can do that, but the gains will be much smaller than if we could avoid the
temporary file entirely.

> In the DataStore implementations an additional temporary file is created for
> every binary uploaded. This step is an additional overhead when the upload
> process itself creates a temporary file.
> So, the solution proposed is to check if the input stream passed is a
> FileInputStream and then use the FileChannel object associated with the input
> stream to copy the file.
