Autodownload slow transfer rate

I all, I’m playing quake3 with friends. One of us will host the game creating a match and sending to others its ip.
The issue we are facing is that he has a 100Mbit full fiber connection but we download from its server at 13Kb/s.

How can we speed up download?

Setting sv_dlRate 1000 will increase downloads to ~100 Kb/s if I remember correctly. For MB/s speeds use a web server and sv_dlUrl "http://host/path/" to point to the web server. In this example the pk3 files should be in http://host/path/baseq3 on the web host.

These are cvars to be set on the game server.
