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.
Execution:: call
Groups:: Uncategorised

Syntax:: [expression(String),Any([parameters]),cycles(Number)] call BIS_fnc_codePerformance;
Parameters:: expression: String - tested expression
: Any (Optional): Param(s) - passed into code (default: [])
: cycles (Optional): Number - Number of cycles (default: 10000)
Return Value:: Nothing

Example 1:: testArray = []; ["testArray = testArray + [1];"] call BIS_fnc_codePerformance; testArray = []; ["testArray set [count testArray,1];"] call BIS_fnc_codePerformance; Compare two methods of adding elements into array

-(Environment: ArmA3 ver 1.14) Please always take advantage of the second and third parameters when running code on [[BIS_fnc_CodePerformance]]! It will be critical if parameters weren’t separated especially when reserved variables looped! E.g.
