Upload speed from NL is too slow. Looks like its capped to 800 kb/s :facepalm:. Always same speed with zoom uploader. I have stoped uploading to fileserve because of that , few weeks ago.
The speed have nothing to do with location, my server is also in NL and i've got very good upload speed with Fileserve 20mb/s to 120 mb/s
the problem could come as well from the high traffic hours on banwidth and your server provider
