DayZ server performance is measured in server FPS: how many times per second the server updates the world. To keep it high, restart the server on a schedule, keep the number of items, zombies and animals close to the defaults in globals.xml and types.xml, and add heavy mods one at a time. Check the result in game with #monitor 5 while logged in as admin, or with logAverageFps in serverDZ.cfg.

​
How to check DayZ server performance

  • In game: log in with #login <password> and type #monitor 5. The server shows performance values every 5 seconds. #monitor 0 stops it. See admin commands.
  • In the log: add logAverageFps = 10; to serverDZ.cfg (Game settings > serverDZ.cfg: open the raw file). The server writes its average FPS to the log every 10 seconds.
  • In the panel: Statistics shows CPU and memory over time. See view server statistics.

DayZ server performance tips

1

Restart on a schedule

Open Schedules > New schedule and pick Restart every 6 hours or Restart every night. Tell players the restart times, for example in your Message of the day. See schedules and tasks.
2

Keep economy numbers sensible

Every item, zombie and animal in the world costs server time. Big increases to nominal in types.xml, or to ZombieMaxCount and AnimalMaxCount in globals.xml, lower server FPS.
3

Clean up faster where it helps

globals.xml sets how long bodies and ruined items stay. Lower values remove them sooner.
4

Add mods one at a time

Large mods, AI mods and many custom map objects add load. Add one, watch FPS for a day, then add the next.

​
globals.xml values that affect performance

Defaults from the vanilla Chernarus mission (db/globals.xml): Stop the server, edit the value in mpmissions/<mission>/db/globals.xml, save and start. Change one thing at a time and compare server FPS.

​
Frequently asked questions

​
How often should I restart a DayZ server?

Many servers restart every few hours. Use a Schedules restart that suits your players, for example every 6 hours, and tell players the times.

​
Does Time speed affect performance?

Time speed only changes how fast the in-game clock runs. It isn’t a performance setting.

​
Can I limit the server FPS?

Yes, with the start option -limitFPS=<value> (the current maximum is 200). Add it to Extra Startup Parameters on the Startup page.

​
My server lags only with many players. What helps?

Fewer heavy mods, normal loot counts and regular restarts. If Statistics shows CPU or memory at the limit all the time, the server needs more resources.
