xjoker_ 25 Posted March 11, 2019 Hello. I'm asking your help to find out what can cause FPS issues on my server.

[2019-03-10 / 22:09:24] Sauvegarde terminée ! There is no AI in this mission. Only players, vehicles, objects in mission.sqm (buildings / addActions / modules to hide objects ... ), and (many ?) sql queries (using extDB3). The command https://community.bistudio.com/wiki/diag_activeSQFScripts shows nothing special on the server except 2-3 loops that are sleeping and save vehicles every 15min I don't think that I will find a more powerfull CPU than this one for Arma. So i'm looking for an efficient way to find out why he's running at 100% and the server goes < 10 FPS with many players. Some servers can host 150-200 players without problems, and with many mods enabled ... I tried to edit the basic.cfg file to "optimize" the network, using the guide on this forum, it had no effect I tried to move all the vehicles on a HC using setOwner, it was worse (desync). So I don't know. What is strange though, is that as you can see on my logs , the server needs less than 1 second to save 18 players - 332 vehicles but more than 40 seconds to save 99 players - 394 vehicles Share this post Link to post Share on other sites
Dedmen 2590 Posted March 12, 2019 Grab the Profiling branch and profile https://community.bistudio.com/wiki/Performance_Profiling https://community.bistudio.com/wiki/diag_captureSlowFrame https://community.bistudio.com/wiki/diag_captureFrame You will want to execute these on the server if the server is at low fps. 21 hours ago, xjoker_ said: and (many ?) sql queries (using extDB3) Are you using "compile" to parse the query results? if so, you should stop doing that. You might want to move your database stuff to your HC if you already have one. 1 Share this post Link to post Share on other sites

I'm using parseSimpleArray for that 58 minutes ago, Dedmen said: You might want to move your database stuff to your HC if you already have one. It's actually a good idea I don't know why I didn't try that before Share this post Link to post Share on other sites

And then copy-paste the text into it to display it. What the lines mean is not documented. Have to apply some logical thinking. Like "nw" is network and "drw" is drawing aka rendering. And "sim" is simulation and so on. I assume your main problem will be extDB calls anyway. 1 Share this post Link to post Share on other sites
