How do I find out what is causing server lag

[SmeLLyArMpiTsXtra]

Hello all. Thank you for your attention.

I notice my game lags / freezes at times. Could you please kindly guide me on how I can find out what is the cause? Do include instructions on how i can accomplish it.

Much appreciated.

is there any errors in the output after you play test like

--script past execution time

Does your game have a lot of parts?
Does your game have any virus from free models?

Hello, You should also include the context which I know is about your wave defense game:

First full game made. Zombie Base Defence. Do kindly take a look

hello community! This is a strategic shooter and hence you need to manage your Command Points for deployment and kill zombies for more points. Tactic matters so you have to consider spending your precious command points on a soldier or a combat engineer to repair the walls. You will also earn Strategic Points that you can use to upgrade / train your soldiers so that you stand a better chance at survival! i made an “AI Director” script which tracks the player progress and adapts accordingly. T…

From the game, I know that the lag comes from when the zombie horde spawns. So try this, during an in-game playtest open up the script performance and view it from the server-side. Plus recording a video of this would be really helpful.

How to measure how Expensive "Code" is

Expensive code does not necessarily mean code which uses lots of memory, it also means code which runs really slow or otherwise bogs down the overall performance of your place. You can use the script performance tool built into Studio to look at some of that performance info: [image] [image] The names of your scripts are on the left. The Activity of a script tells you how expensive it is to run. Lower is better! There’s more details on this page about diagnosing and fixing performance issue…

Usually, when the server is doing a lot of math it can obviously cause the entire server to lag as it would have to be concerned with client-side replication and stuff. So the first bet would be to check the script activity there.
