Slow speeds when sharing files via UGOS links on Ugreen NAS

Hi everyone!

Has anyone noticed that file transfers through the “Share” links in the UGOS system (on Ugreen NAS devices) are quite slow?

In my tests, download speeds stay between 5 and 10 MB/s, even with a good internet connection and a fast local network.

Has anyone achieved better speeds or found a way to optimize this (for example, using DDNS, VPN, or advanced configuration)?

Any comments or insights would be very helpful!
