Server The Server release of Bionic Beaver sports a much-improved installer and a new, smaller ISO file for a minimal install option. Why did Ubuntu 18.04 slow. Download: 3837.55 Mbit/s Testing upload speed. Any thoughts on why the upload is so slow compared to the download? Make the file executable: I'm running an Ubuntu 18.04.2 on my droplet, I have NordVPN. Some antivirus software may do intensive scans of each of these files during startup and block access until those scans complete. If the problem began after.
Only other thing I can think of is that FTP is using a passive connection in Linux, but not in Windows. This would happen if the firewall was enabled on Linux. I pulled that file with wget and saw on average about 1.2MB/s. Without doing any more research, I would assume it was throttled on the other side.
The speeds ranged from 0.5 MB/s to 1.8 MB/s. I'm on a commercial ISP without any connection issues.
Using a browser to get the FTP file, I saw similar speeds as wget.
I also tried modifying some network stack parameters which claimed to solve this issue previously. For me, those changes reduced the download speeds about 40%. The settings were net.ipv4.tcp_rmem and net.core.rmem_max, if you'd like to look them up.
I'll keep watching for solutions. Generally, if I'm using FTP, I kick off the task in a different window and don't worry about it.
