("fast download" lmao)

Fast download doesn't refer to the literal speed of your downloads, that is always relative to your internet connection.. it refers to a feature of source dedicated servers that lets users to download content through a proxy download server with high bandwidth instead of being limited to the source engine's 30KB/s bandwidth cap for client connections

Also server performance isn't determined by just a static number of addons added.. its the actual performance cost of the code ran per server tick. Adding 20 playermodels has no impact to server performance, but adding 20 SWEPS that all have really convoluted and slow features will, especially when that code has to run 120 times per second during a giant firefight.
