Server Config Information

Default LinuxGSM installs have configSubDir=servername set in the command line which will set your priority config files to be in /home/user/serverfiles/KFGame/Config/kf2server directory, use these files to change settings on your server.

Workshop Content

Killing Floor 2 supports Steam Workshop.

High disk IO using Steam Workshop

As of March 2020 Killing Floor 2 servers will check workshop files at server start and when map changes occur.

There is a potential problem with Killing Floor 2 dedicated servers using the steam workshop to host content that causes the server disk usage to constantly read/write at 100% and could damage hardware.

To avoid this problem try to keep the amount of workshop content as low as possible. Alternatively, it is possible to convert workshop files to fastdl. However, fastdl is no longer supported by Tripwire and files are not compressed, which increases download times.

Disk IO can be monitored with the ioptop command.
