FastDL (Fast Download) is a feature that speeds up how players download custom content - such as maps, models, and textures - when joining your Garry’s Mod server. Instead of relying on the Steam Workshop, FastDL uses a web server to host and deliver files directly to players, significantly reducing loading times and improving the overall experience.
Before setting up FastDL, make sure you have:
A web server with FTP access and a live domain.
An FTP client (like FileZilla) to transfer files.
The custom map or content already installed on your Garry’s Mod server.
Follow these steps to configure FastDL for your server using the ChipHead Panel:
Log in to your web server using your FTP client.
Create a new folder named garrysmod in the root directory of your website.
Upload your custom map folders and any other required content into this directory.
Log in to your ChipHead Panel.

Stop your server.

Go to the Files tab.

Add the following lines to your configuration file:
sv_downloadurl "http://yourwebsite.com/garrysmod"
sv_allowdownload 1(Replace http://yourwebsite.com/garrysmod with your actual FastDL URL.)
Click “Save Content”.

Start your server.
