Each download does a
HEAD
before theGET
, but unless the file is possible a very large file that would benefit from multipart download, then this is just adding unneeded operations and delay. This PR changes it so thatmultipart_threshold
being 0 will skip theHEAD
call and I'd argue that this should be the changed to the default behavior as wellRelated to boto/boto3#3083
