Game runs in slow motion mode AGAIN

[Dopium]

^^With that said, does it tend to happen after mesecon machines are built? Not sure if its the problem but, i have seen servers plummet to a crawl if not crash when large or multiple mesecon inventions are activated.

Some popular servers had/have any "strobe" effect ABMs removed because of the lag it can cause. Example the blinking flower and such will pulse lights/pistons on and off creating lag that can sky rocket.

Source: I used to make, mesecon nuclear reactors and model engines all the time. Member capfrap decided to copy and make a bigger and better reactor, well it was that much bigger and better, it crashed the gameboom server :). What a laugh it was, anyway bad_command worked out the blinking flower from mesecons was the issue

I won't say we have plenty of mesecon "machines". But we do have plenty of automated systems that use the mesecon blinking lights. If that is the problem , then it means one can't have any automated systems without it as I don't know of another way to activate/trigger things like chest filters and node breakers. That would mean you could only have normal game speed if you have no automated systems on your server , which would be bad. :(

@Dopium: As a test I removed all non-essential mesecon blinking plants now. Mostly all node breaker trigger ones.
And I can defnitely see an improvement. Game speed is now at roughly 60% , which is a big difference from what it was at 20%.

This is a big problem though , mesecon blinking plants is vital for all automated systems.

Yeah may very well be the issue, the gameboom server still had mesecons but only manual switches and solar panels. ABM's that were using loops like the blinking plant/lights were removed.

Im not exactly sure but i think some mesecon ABM's sync with server time when looping or something like that. Having many automated/mesecon systems will most likely overload the server with update requests.

As it turns out this didn't solve the problem. The mentioned improvement lasted only for a while and everything was back to slow mo again. So the mesecons blinking plants wasn't the cause.

Is the server also the same machine your client is running on? Minetest server really doesn't use that much ram. But if you are also using the same machine to play the game using a client... your client will consume MUCH ram. Eventually lots will be stored in swap. If that is the case, your server will crawl. Really crawl. It happens quite quickly if you are using a texture pack with higher res images. Also if your world is larger and you have people off exploring in uncharted area.

Nope , my server is dedicated server only. Client connects from another pc.
Server never reaches past 30% ram and cpu usage.

Yesterday I updated both the engine and subgame I use. After that last night and still today it's running at normal speed though. I changed no settings or anything other than the mentioned updates and it runs like a dream today.
And I start the server up with a different command syntex since last night due to another error I encountered.
So either something that updated in the engine or in the subgame resolved it *for now*. Holding thumbs that it stays as is now.
( unless the different command syntex I use now to start the server has something to do with it )

Well, scratch that theory. We're trying :)

hehehe yeah , will keep on trying and it will keep on bugging me until it's solved.

But from what I have seen since yesterday is that it have to be one of the mods in the subgame or the engine itself. That's the only things that I changed yesterday and it is still running beautifully as we speak.

Ok then travelnet + travelpoints = slow motion???

Nope. If you read just the next post after that I stated that wasn't the issue.

The problem stopped when I changed my command syntex for starting the server.
I always used mintestserver --worldname ..........
Then after an update to the engine minetestserver didn't exist anymore and I had to switch to :
minetest --server --worldname ........

Then from there my game speed was fine.

That's because the cmake flags were changed, you can still enable building the minetestserver executable by hand

I ALWAYS used minetest --server, so I never had problems.

But WHY was minetestserver building disabled by default?

I guess it's just because most players only use the client, and if they compile a development build it saves some time...
