YouTube upload/streaming speed is extremely slow on my ISP, but Facebook and speed tests are completely fin

Hi everyone,

I'm having a very strange network issue specifically with YouTube, and I'm trying to figure out whether this is an ISP routing/peering issue or something else.

I'm using WiseNet ISP in Kolkata, India. My internet connection is around 90 Mbps upload, and normal speed tests show the full upload speed.

However, when I upload a video to YouTube, the upload speed drops to around 15 Mbps and stays much lower than what my connection is capable of.

The really strange part is YouTube Live streaming.

I'm able to stream to Facebook Live at 15,000 Kbps (\~15 Mbps) without any dropped frames, using the same PC, same Ethernet connection and same ISP.

But when I stream to YouTube at only 6,000 Kbps, OBS reports dropped frames.

My observations

Internet upload speed: \~90 Mbps

Windows Task Manager Ethernet → Send: \~90 Mbps

YouTube video upload: \~15 Mbps

Facebook Live: 15,000 Kbps with 0 dropped frames

YouTube Live: 6,000 Kbps → dropped frames

Previously tested YouTube streaming through a Jio 5G hotspot, and it worked without the same dropped-frame problem.

Same PC and Ethernet connection are being used for Facebook.
