I am seriously shocked, what did you do with the fastest protocol BitTorrent so it performs slower then a regular FTP encrypted transfer.?!
I did find a few topics in this forum about the slow transfer speed, but non of the tips does any difference.
In two words, my continuous test with 20GB of data on a regular 100mbit Broadband shows steady results of download speed ~12mb/s - FTP vs, ~7mb/s - Resilio
All settings are default, using Windows 10 LTSB, Core i5 8GB ram and regular hdd.
Note: FTP connection is also encrypted with strongest TLS certificate.
