-===Trust but verify? (C)===
-It is strange that in the article aren't given the source code of the tests.
-I myself decided to compare the speed ''for_from_to_do'' and ''while'':
- #define __prflrStart diag_log "profiler start"; vdmj_diagProfilerTime = diag_ticktime;
- #define __prflr(text) diag_log (diag_ticktime - vdmj_diagProfilerTime); diag_log text; vdmj_diagProfilerTime = diag_ticktime;
- #define __maxCount 1000000
- __prflrStart
- __prflr("for begin")
- for "_i" from 1 to __maxCount do { };
- __prflr("for end")
- __prflr("while begin")
- _whileCounter = 1;
- while { _whileCounter <= __maxCount } do {
-     _whileCounter = _whileCounter + 1;
- };
- __prflr("while end")
-;
-usage:
- call compile preprocessFileLineNumbers "profiling\loops1.sqf"
-output:
- "profiler start"
- "for begin"
-.898438
- "for end"
- "while begin"
-.0351563
- "while end"
-WTF?
-I'd like to see in article description of the method of testing, and sqf code of the tests. Thanks
