Summary of the bug:
Downloading a file using https protocol is too slow. Download times out
frequently. This happens when ffmpeg is built with gnutls on macOS.
This performance decrease is caused by
https://git.ffmpeg.org/gitweb/ffmpeg.git/commit/70d8077b795766e2486e6ec8110f22a97362d6d6.
If you checkout master using a previous commit e.g.
a1553b0cfbff92223caaed4103b92373b2339173 the same file is downloaded in 35
seconds.
See attachments provided.
