Because the servers in the data center are bound to a small bandwidth, this post is mainly about using Dante to provide SOCKS5 forwarding, using some high-bandwidth servers for traffic forwarding to speed up dependency package downloads. 1. Find a High-Bandwidth Server Install speedtest-cli 1 pip3 install speedtest-cli List peer test servers 1 2 3 4 5 6 7 8 9 10 11 12 13 speedtest-cli --secure --list Retrieving speedtest.

1.
