Original GitHub issue: https://github.com/GameServerManagers/LinuxGSM/issues/949

I've noticed a long time ago that when you attach to any tmux sessions that are being used by csgo there will be a delay on input in that session. I figured out that this is caused by the default configuration files setting sv_hibernate_when_empty to 1, which may annoy other people who haven't figured this out yet. You can also modify how many milliseconds to sleep per frame by using sv_hibernate_ms, if users want to keep the server in hibernation if there are no active players, but still be able to interact with console normally they should set sv_hibernate_ms to 5. I think by default lgsm-default.cfg for csgo should include sv_hibernate_when_empty 0 for ease of use.

Hi,
Server hibernation by default is a good thing to keep in my opinion to save some CPU power in a lot of cases.
But, sv_hibernate_ms sounds like a good idea.
However "sv_hibernate_ms x # of milliseconds to sleep per frame while hibernating" > what the hell do they mean ? Does it hibernate more if you increase the value ? Is it useless under a certain value ? Is it freezing over a certain value ? We'd need to clarify that before.

It looks like it reduces the amount of ticks per second that the server handles as you increase the latency. If you set sv_hibernate_when_empty to 1 and sv_hibernate_ms to 0 it seems like it uses the same amount of CPU as if you had sv_hibernate_when_empty set to 0. So you have to assign a value to sv_hibernate_ms in order to decrease the amount of ticks that are updated per second, which should in turn lower CPU usage but it's almost negligible how much it actually saves. It seems like even adding an entire 100ms between each tick update saves only about 1% of CPU usage compared to having sv_hibernate_when_empty set to 0.

OK, so that's about what i thought. But it still doesn't give a precise way to interpret it.
Do you know what's the default sv_hibernate_ms then ? So that we can lower it accordingly.

The default sv_hibernate_ms is 20

And between sv_hibernate_ms 5 and sv_hibernate_ms 20, console still doesn't work properly ?

Having it set to sv_hibernate_ms 5 allows acceptable interaction with the console. Anything higher is extremely annoying, you can still use the console, but it's very annoying.

Well

Should do the trick then. :)

I'm noticing that csgo config is quite empty. Do you think about anything else that would be worth adding ?

It might also be worth adding host_info_show 2 to allow game-trackers to query the server and host_players_show 2 to show what players are playing on that server, as well as host_name_store 1 to show the host name in queries as well. Most community servers will usually want to have this enabled by default. There are quite a few other things that could also be included, but it would require input from the user during installation.

That looks good, it's sad that official documentation from valve is usually either outdated or hidden somewhere on an obscure page and people have to spend alot of time to figure things out.

From what i know, there is no actual official documentation from valve. It's a wiki, so anyone can write it, as i did for Rust, because when i needed it, i found information in it to be quite poor.

I think this is solved. If you got more suggestions for the default config, or even things that people might wanna change that we could put at their default value, don't hesitate to share it. :)
