Description

Description:
BIS fnc codePerformance.png

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. Upon function execution, window with results is opened. The user then has a choice to copy the result into clipboard or not.
This function is using diag_codePerformance command.

Use toString to stringify Code, as str adds curly braces - See Example 2.
Execution:
call
Groups:
Diagnostic

Syntax

Syntax:
[expression, arguments, cycles, display] call BIS_fnc_codePerformance
Parameters:
expression: String - tested expression
arguments: Anything - (Optional, default []) arguments to pass into the code
cycles: Number - (Optional, default 10000) number of wanted cycles
display: Display - (Optional, default findDisplay 46) display in which the message window with results will be opened. Use displayNull to disable the window
Return Value:
Number - average execution time of the expression

Examples

Example 1:
// compare three methods of adding elements into array testArray = []; ["testArray = testArray + [1]"] call BIS_fnc_codePerformance; testArray = []; ["testArray set [count testArray, 1]"] call BIS_fnc_codePerformance; testArray = []; ["testArray pushBack 1"] call BIS_fnc_codePerformance;
Example 2:
[toString { hint "Hello there" }] call BIS_fnc_codePerformance;
