Opening the video and letting it play till the end, I found the following in my browser's debugger:
- 63 XHR requests
- 52500 Kbytes of content in total
- 42020 Kbytes of content in video data
- 1600 Kbytes in Javascript
- 0.36 Kbytes of title (repeated, 14 times)
What does this tell me? That the title is 0,000686% of the total transferred content for this video.
I'd be more worried about the 1.6 megabytes of executable code (that's two thirds of the original DOOM) just to basically embed a video player and a list of comments.
Out of all performance issues you can complain about (enough with the useless polyfills to artificially slow down Firefox already, Youtube staff!), repeating the title is not the important part.
