Power saving for idle Linux servers
If you run an idle Tribes 2 Linux dedicated server in your basement, this could decrease your idle power consumption.
It might work on Windows and with bot servers but I haven't tested on either. Bot servers will likely need better player count checks.
I want it, what do?
Add the script to your mod/scripts/autoexec/ folder or exec it as part of your startup scripts. The script has no effect unless the game launched in dedicated server mode. It will increase your minimum ping to 32ms when no players are connected.
An i7-7700K powers https://twitch.tv/t2vault - this consumes around 120 watts.
After starting a Tribes 2 dedicated server, the power draw increases to 220W: an extra 100 watts! The dedicated server takes up 8% of this aging 4c/8t processor.
I realised that the server's sleep per iteration is only 1ms. With the Linux task scheduler and a mostly idle core, this is actually 1ms, so the dedicated server does a lot of nothing very fast.
Obviously, I don't want to give players a bad experience but I also don't want to double my power bill if I don't have to.
A happy middle ground seems to be setting that sleep to 32ms or higher and resetting it to 1ms when the server has active players. A 32ms sleep was enough to push my process into the 0.5 to 0.7% consumption zone without severely affecting ping. I actually run it at 50ms which hides it's consumption in the noise of the vault stream.
All copies of Tribes 2 are executed through the current version of Wine, 8.8.
