What is StackTraceUtility?

As you can see, StackTraceUtility.ExtractStringFromExceptionInternal is taking so long time in my development build in Android device.

My question is what is StackTraceUtility, and will it costy in release build?

 

This is followed right away by "LogStringToConsole". You probably have (uncaught) exceptions occurring and the time is spent on those (regularly occurring exceptions (despite being caught), should better be avoided in C#).
Also saying just in case: Don't use Debug.log() in the Update method (like printing every single frame). That can even deteriorate performance on desktops and Unity does not remove them in release builds because it can still be meaningful to log from builds (log is saved somewhere in %appdata% on desktops).

 

LogStringToConsole takes 0.5 seconds, while StackTrace takes 11.

All of that happens within Self while the function is called only 27 times.

 

Nice way, I will try ChatGPT by myself

 

It's the thing which generates stack traces, i.e. prints the hierarchy of calls in log messages and errors.

It's expensive, but shouldn't matter for performance as you shouldn't be logging stuff often, and you shouldn't be hitting errors or exceptions, ideally, at all.

Also, in a release build it doesn't fully track this stuff anyway.
