As far as I know (jacadcaps may correct me on that), the root cause of this issue has not changed during the last 16 years of MorphZone discussions: ancient overall design of NetStack (especially missing TCP window (re)scaling feature) and the ancient SANA-II interface.
As the issue is much less severe with local connections, the only feasible workaround is connecting to a proxy (Windows, macOS, Linux...) in the LAN that handles the actual WAN connection.

@jacadcaps
Thank you so much for showing me how to fix the problem. Now that I’ve enabled a local proxy server, everything is working perfectly :)
As shown in the image below, the two files are now downloading at 16 Mb/s (vs. 1.8 Mb/s) and 24.5 Mb/s (vs. 4 Mb/s), respectively

To achieve this, I simply kept the SSH service running on my local host and enabled the proxy on port 8080, creating this simple script to run when needed

Code:

Regarding what was discussed in the thread, I can confirm that YouTube videos at 720p work perfectly for me (without any lag or synchronization issues between video and audio)

@Andreas_Wolf
thanks for the explanation; your reply actually answered the very question I was about to ask @jacadcaps about why this happens
Everything is clearer to me now

Will it finally be possible to fix this in future versions of MorphOS?
