youtube.com is too slow
OS version : Windows 10 Pro 21H2 Browser version : Firefox Developer Edition 126.0 Beta 8 (20240501022718) Platform : windows, Web
EVERYTHING especially
* The time to receive the first HTTP response when connecting * the time to call up the various css elements that make up the screen * the time to call up the img elements on the screen is too slow.
tooooooooo slow. I waited 36.6s until http response for every new URL open! Of course, I am using a lot of Firefox extensions, but there were no serious problems outside of YouTube, and the same problem occurred after removing the extension, and i also confirmed that the problem caused by web extensions on waterfall(on firefox profiler) was minor.
I can't even guess the cause of the problem, so unfortunately there seems to be no additional information that I can give you. I'll keep following up as long as I can. I will attach some pictures that might help you solve the problem. and you can also approach to my full-recorded firefox profiler data

Provide a link to a video. Where are you (State or Country)? Who are you using for DNS? Lan or WiFi? Laptop, desktop, or DIY? Can you create another user, use this add-on to show how long YouTube takes.
This only took 2sec for me in New Jersey, plugged in. see screenshot https://www.youtube.com/watch?v=e6OQkwSvyVc
Where are you (State or Country)? : Gwangju, Republic of Korea
(Up/Download speed for my network is 240Mbps/213Mbps, 43ms. Midean of 10 test) (what's going on upload speed!!!)
Who are you using for DNS? : idk(i'm not good at Network, sorry for that, if this is major, please notice me.) Lan or WiFi? : WiFi, unfortunately. Laptop, desktop, or DIY? : Desktop.
my setup is pretty not bed. Ryzen 2600, DDR4 48GB, rx570, OS on SATA ssd.
note : i know this is poor condition for network, but i used this setup for 5 years, and of course, it wasn't very fast before, but it wasn't as "CRITICAL" as it is now. During last half of year, my firefox is starting to slow down, it's been noticeably slow for the last 3 months, it's been unbearable for 2 months, and now I'm afraid to click on YouTube links. it's a gradual change, but it suddenly slowed down at a certain point.
There is the same symptom on a some other webpages, but not Critical. There are days when symptoms are severe, or not, but and YouTube has the largest gap in symptoms. and today is not severe day.....
i've tested few cases, which is "onSecretTab or not", "youtubeMainPage or givenLink", "clearedOpen or cachedOpen". (I thought pages already open in the same window would be cached) the median value was obtained by conducting 5 times for each case. The results were as follows.
- secretTab_youtubeHome_cleared

- singularity :
* at "secretTab_givenLink_cleared", it was highly-skewed to both side * in every secrettab simulation, the "Wait for Sub Resources" was domain issue, in ather side, in nomal tab simulation, the "DOM Parse" was domain issue, only except "tab_youtubeHome_cleared" * "Wait for Sub Resourses" issue was founded in FireFox profiler either
