Description of your issue, suggested solution and other information

The time taken to "print title only" for a single video is too long. I checked this with channels/playlists as well and it seems to take approximately 112 seconds to process one video. I also checked using other programs that are dependent on youtube-dl and the result is the same.

Does anyone know why it is so slow? Does anyone else experience the same slow speed of processing?

Hi, I did post the complete verbose log. Could you please check again?

I tried on an old youtube-dl version (2018.11.03)
and an old Python version 2.7.15rc1
and the current versions and all gave ~3s

Sure 3s is slow compared to some 0.4s hack;

> time curl -s https://www.youtube.com/watch?v=UAor3YnvcQ4 | grep "\" title=\"" | grep alternate | tail -n 1 | perl -pe 's/.*="//g;s/".*//g'

But youtube-dl focuses more on getting it done than getting it done fast.

I tested on Windows 10 and it was about 4s (can't be bothered to try and find timeit.bat etc).... so maybe check another computer or your network.
