SLOW download via normal FTP.
After several years of using WinSCP, it stopped downloading faster than 100 to 200 kB/s as of Jan 12, 2021. I use it exclusively on DriveHQ (DHQ). The DHQ file manager downloads at 2 to 3 MB/s. I upgraded to beta 5.18.1 and still have pathetic download speed; sometimes it disconnects. My internet speed test is always over 50 MB/s, regardless of where the server is that I connect to.
