Introduced in

Game:
Arma 3
Version:
0.50

Description

Description:
Measures how much time it takes to execute given expression. Results may vary based on overall performance; use this function to compare alternative scripting approaches rather than to measure specific values. In Arma 3, window with results is opened afterwards. NOTE: For best results restart your client before conducting tests. This function uses diag_tickTime which loses its precision the longer the client runs from restart.

Nothing

(ArmA3 1.14) Please always take advantage of the second and third parameters when running code on BIS_fnc_codePerformance. And it is not suggested to use reserved variables under scheduled environment. E.g. [' [ { a = _this } ] spawn { private "_code"; _code = [_this, 0, {}, [{}]] call BIS_fnc_param; { _x call _code; } forEach allUnits; }; '] call BIS_fnc_codePerformance; There will be a great latency until GUI being displayed, never do like that, on the contrary, we should: [' { private "_code"; _code = [_this, 0, {}, [{}]] call BIS_fnc_param; { _x call _code; } forEach allUnits; }' , [ {a = _this } ], 1000] call BIS_fnc_codePerformance; As for the third parameter, only run the code with desired loop and not always 1000 times like the default set: [‘ a = 0; b = true; for [{_i = 0},{_i < 10 && b},{_i = _i + 1}] do { a = a + 1; if (a >= 7) then {b = false}; };’ ,[],1000] call BIS_fnc_codePerformance; //Sometimes such 1000 loops will freeze the game directly. So separating all three parameters and using them wisely are recommended.
