Server performance with scripts

[freebirddz]

Hello Folks,

Does the use of scripts in MP, affect the performance of the server ? if Yes, how can we optimize that or how to get scenario work without impact on performance ? :music_whistling:

 

 

Thank you and have fun.:pilotfly:

If server performance gets "infected", try using an antivirus :D

 

Now seriously, the number of units / missiles on the map is the main factor to consider.

Anything that does anything will affect performance to some degree...as Hardcard says, the number of units running will be the main factor because of their own AIs and because they will have a cascading effect on everything else you've got going on.

 

Running EWRS? 1 unit on the map and 1 EWR site, no problem. Checking the position of 80 aircraft and comparing it to the picture from 20 different EWR sites? Might start to see a bit of a bottleneck.

 

Some units are more processor intensive than others, notably long range SAMs, as they have to constantly check huge volumes of the map for units and compare that unit's behavior against what the system is capable of detecting to determine whether it "sees" the aircraft. A moving unit is more processor intensive than a static one as that unit must constantly check for obstructions and, if necessary, re-route its path around them.

 

Ultimately, it's up to you to find the line between what you consider to be acceptable performance and the volume of units in-game and there's nothing really set in stone. User hardware will also play a huge factor in where that line is. ED are continuously working on netcode and optimizations as the dedicated server matures, so things change over time as well.

In my experiences over last few years, SAM's EWR and lots of moving ground units seems to effect performance the most

This is some good info guys. think i noticed a nice performance hit when I added a couple more EWR's.

of course it does.

check your script to trigger on specific event and not to test all units and zones every seconds.

regarding your script engine (...moose / Ctld/ ATME / MIST / other ...) you must be aware of how to optimize events handlers and not using a timer to test unuseful data when not needed.

 

but this advice : the more unit the more lag, is true, and it is more noticable if you don't care what i said above.

Finally checked out your server the other night. You're doing some excellent work in there, happy to help. :)

Hhhhh, thank you and sorry for the mistake :P affected YEAH

 

 

1. Use less moving ground units.

2. Use less EWR

3. Use Triggers not timers

4. For the use of Scripts engine be aware of how to use events, and continuous reversion of the code.

5. Learn from users feedback

 

 

Thank you ALL.

1. Moving or not, the mere presence of units (even statics) on the map will be the main performance hitter (according to my tests).

 

2. Sure, EWRs might impact performance more than regular units, but I'd need to run further stress tests in order to confirm it.

Contrary to what I thought, enabling AI for AA vehicles (radars included) has a pretty negligible impact on performance (at least that was the case in the stress test mission I created).

 

3. Depends on the triggers and timers. Continuous or switched condition triggers in ME are as "bad" as continuous schedulers (timers) in scripts.

I'd recommend setting up your triggers / scripted schedulers so that they only run when needed.

Also, as feefifofum mentioned, be careful with "heavy checks", they might clog the game if you abuse them.

 

But, anyway, in my experience, the number of units / statics on the map will impact performance much more drastically than inefficient combinations of triggers and schedulers.

 

 

4. Event handlers are super useful, so, yup, take advantage of them.

 

 

5. Generally, yes.

However, keep in mind that plenty of users out there aren't computer savvy, they might blame their performance issues on your server when, in reality, the problem is on their end. ;)

Tacview has quite a big impact on this. Will just link to an old post of mine:
