I was downloading the veloaustralia-oceania.exe map from ftp://ftp5.gwdg.de/pub/misc/openstreetmap/openmtbmap/odbl/velomap/continents. When I perform the download with Directory Opus, the download averages about 320Kb/s. If I download the same file with Filezilla, it downloads at around 1.1Mb/sec. If I perform the download with wget, it also runs at around 1.1Mb/s. I went back and tried the download a second time with DO in case there was some caching taking place on the 2nd and 3rd attempts with Filezilla and wget, but the throughput was still only about one third of that achieved with the other two programs.
Why is DO so slow for ftp downloads? I'm running DO 12.7 x64 on Windows 10 x64.
