If you're far away from San Francisco, California, USA (where the Internet Archive server is located), the uploading speed is very slow.
A way to boost uploading speed to the Internet Archive is connecting to a VPN server located in California, which is close to the Internet Archive's location. I would recommend paid VPNs such as Proton VPN.
I have Proton VPN's Plus subscription. Tried connecting from Vietnam to a Proton VPN server in San Jose (which is close to the Internet Archive) and uploading a 4 GB file to another Internet Archive account, and that's much faster than without a VPN. Tried Los Angeles also, and the speed isn't much different from San Jose for me.
