Description
We noticed that the FTP transfer on Linux is very slow: ~ 1 KB/s while it is expected to be MB/s.
Downloading from the same FTP server, but with different FTP client, has the expected high speed.
The issue is reproducible with different FTP servers. For example, this public FTP server of NASA [1] is also good for reproducing the issue.
The issue is not reproducible on Windows and Mac, but only on Linux (tested with both Ubuntu and Fedora).
We were able to resolve the issue by replacing the current Apache Commons Net library version 3.2 with the latest version 3.4. It looks like there are some performance issues recently fixed in the Apache Commons Net project.
We should request Apache Commons Net 3.4 to be included in Orbit and use it in RSE.
