Pausing high load services during gaming (swg-empire.de)

I'd like to disable some services that might decrease my gaming performance while a game is running. Stuff like search indexing, automatic updates, filesystem tasks.

Has anyone done something in that direction?

My spontaneous idea was to use gamemode to switch to a systemd target that disables those services. Although I'm not sure if systemd targets actually can disable services or if they can only start them. Might also be a little overengineered.

If I don't get a better idea I will just run a start and stop script with gamemode to handle all that. Although I'm not sure if that would be able to stop system services. Will cross that bridge when I get there.

Edit: While I can automatically stop services by starting a target they aren't started again after stopping the target. I guess I will just use some simple start-gaming and stop-gaming scripts.

Yes, you're right!

In my case starting timers.target stops my gaming.target and restarts all the timers gaming.target had stopped.

Edit: I don't want to use isolate because I'd rather blacklist the services I don't want.

Sorry for the series of edits. Yeah, just starting timers.target or graphical.target again when you're done without using isolate seems like a pretty good strategy!
