When using Rclone browser are loading slow

OS: Windows 10
Rclone ver: 1.47.0

When I use Rclone to do server-side --disable copy from Gdrive, my web browser are loading all the website slow(it is keep loading and loading), when I stop Rclone, the web browser become normal and can load all the website fast.
ps: It is not my internet speed problem, as

, and this situation didn't happen before, just start arising these few days.

You would need to either limit your bandwidth on rclone or traffic shape on your router.

—bwlimit to something that fits your setup.

Just update my Windows to 1903, and the problem gone, everytime there is a Windows update, and my pc will act weird.
