Applied Energistics killing TPS?

Golrith · Oct 16, 2013

On my custom mod pack/server we discovered that TPS was getting really low, and that by disabling the AE networks TPS was restored.

There were only 3 separate AE systems in place, each one using between 78-200 power, so not overly massive.

Anyone else encountered this problem and been able to fix?

What in the world is TPS?

Ticks per second. Optimally, it's 20, but server lag can diminish it (both in single player and multiplayer).

Golrith · Oct 17, 2013

Indeed, with 3 AE systems, our TPS is dropping to 3-4. Turn them off, 18+TPS.

Lathanael · Oct 17, 2013

It is complicated. Without knowing the exact setup we can not tell you if it is AE causing TPS drops or any other system which is handled by your AE system and also gets shut down when AE is down.

Golrith · Oct 17, 2013

Indeed. Since we are going to restart our world soon anyway, we can easily "dismantle" the systems and test each connection and TPS effect.

As far as I know, the AE systems are interacting with:
MFR
Mekanism
Forestry
Extra Bees
Thermal Expansion
Translocators

pretty much this. it isn't as easy as people think it is to make a custom modpack. though it may seem that everything is working together and there's no visible issues, behind the scenes it could be that mods are fighting with eachother, so it's very important to manually test custom modpacks alot, and always keep an eye on the console

Yep. Omega Dawn has been running and testing for two months. It's just recently due to the increased difficulty that multiple AE systems has been possible. Due to some recent additions/changes to the pack, we've decided to restart to ensure everything is as expected from fresh.

Any alvearies there? They were pretty notorious tick munchers in my previous world.

Golrith · Oct 17, 2013

As far as I recall, only one alvery. I don't believe it's actually connected to the AE system though (someone elses base).
Oh, also forgot to mention it interacts with LP too at two of the 3 locations.

Is there an (easy) way to hook a profiler to the server and see what classes it's spending time in? I know we can get somewhat of a profile in-game with F3 but my understanding is that's client-side.

Trunks9809 · Oct 17, 2013

Theres a server-side mod called TickProfiler that you can add and run to get an idea of what your most 'laggy' entities, TEs etc.

draeath · Oct 17, 2013

Awesome! Found it.

https://github.com/nallar/TickProfiler
http://nallar.me/buildservice/job/TickProfiler/ (1.5.x at the moment)
http://nallar.me/buildservice/job/TickProfiler-1.4.7/ (1.4.7)

Looks like no 1.6.x support though, which isn't an issue for me specifically but others might be a bit down about that

draeath · Oct 17, 2013

Anyone know how to use this?
"Usage: /profile [e/(c [chunk x] [chunk z])] [time=30] [dimensionid=all]"

I don't understand what [e/(c chunk x] [chunk z])] is asking for. (I get the chunk X/Z but I don't see if those are optional compared to 'e' and 'c' etc)

Golrith · Oct 17, 2013

Having the same issue dreath

I'm trying to work out how to specify the dimension, so I can analyse different builds independently.

I connected 2 of the 3 AE systems. No issues in TPS. Connected the 3rd, when from 18 TPS to 3 TPS.
Ran a profile /profile e (the e stands for everything) and it's telling me that it's tileLPinterface causing the issues. Odd thing is is that the 2nd AE system is connected to LP, but I believe the 3rd AE system is not. Unfortunately the guy on the server who knows LP isn't on at the moment, and I don't yet understand the ins and outs of LP

draeath · Oct 17, 2013

Just a note, I set it to write out into a text file every 15 minutes and it's doing that all on it's own, no input from me required

So in the worst case, you've got that data.

can you do a "dump" command instead and then put the contents of that file in a [ code ] block here on the forum? Should be much more readable.

EDIT: I wonder if there's a loop on that arrangement perhaps. Is it drawing more power than usual?

Golrith · Oct 17, 2013

Good news is that my TPS problem is solved. A users build put AE and LP into a communication loop, hence the confusion over thinking it was AE.

Lovely high TPS now. Thanks Trunks for mentioning TickProfiler, that really helped.

I know the issue from the OP is resolved, but I figured I'd address this
/profile e [time] [dimensionid] will profile all entities, default time is 30sec, default dimensionid is all
/profile c [chunk x] [chunk z] [time] [dimensionid] will profile the specified chunk, defaults as above
