How to set the max bandwidth rate in GMod
Type sv_maxrate 0 in the server console to let clients use unlimited bandwidth, or a value like sv_maxrate 100000 to cap it in bytes per second.
sv_maxrate
Sets the highest bandwidth rate, in bytes per second, a client may use; 0 means unlimited.
sv_maxrate <bytes/sec> Examples
sv_maxrate 0 No cap.
sv_maxrate 100000 Cap each client at about 100 KB/s.
Arguments
bytes/secRequired- Maximum rate, 0 for unlimited.
What it does
Caps how much data the server sends to each player per second. Lower it only if the server's upload bandwidth is a bottleneck.
The game's own description: Max bandwidth rate allowed on server, 0 == unlimited
Run it on your server
On a SLASHPLAY server, type it in the Console tab of the server page; the reply shows right under it. A value set there lasts until the server restarts. To keep it, add the line to garrysmod/cfg/server.cfg. New to this? Start a GMod server first.
