StungStang Posted May 17, 2012 Share Posted May 17, 2012 Hi to all, i want to Enumerate all the key of two certain registry key, the number of keys is almost equal, but the scan times are very different, this is an example script with it's result: Global $count $int = TimerInit() _Reg_Enum("HKCR\CLSID") $end = TimerDiff($int) ConsoleWrite ("Time for scan " & $count &" keys in HKCR\CLSID ===>: " & $end & " ms." & @CRLF) $int = TimerInit() _Reg_Enum("HKLM\Software\Classes\CLSID") $end = TimerDiff($int) ConsoleWrite ("Time for scan " & $count &" keys in HKLM\Software\Classes\CLSID ===>: " & $end & " ms." & @CRLF) MsgBox(0, "", "Done!") Func _Reg_Enum($r_key) $count = 0 $Ch1 = "" While 1 $Ch1 += 1 $readR1 = RegEnumKey($r_key, $Ch1) If @error <> 0 Then ExitLoop $count += 1 WEnd EndFuncThis is the result :Time for scan 3776 keys in HKCR\CLSID ===>: 77513.6734796813 ms. Time for scan 3762 keys in HKLM\Software\Classes\CLSID ===>: 157.024587458746 ms.As you can see scanning the "HKCR\CLSID" that have only 14 more key than "HKLM\Software\Classes\CLSID" require ~ 1,30 minutes when the "HKLM\Software\Classes\CLSID" require only 157 ms. How is possible? There is a way to speed up that? :/Hi! Link to comment Share on other sites More sharing options...
GEOSoft Posted May 18, 2012 Share Posted May 18, 2012 Thats because of the way Windows handles those hives. For HKCR it is more stringent about checking security credentials for the logged in user.For more information on the Windows Registry go to the foillowing page.http://en.wikipedia.org/wiki/Windows_Registry George Question about decompiling code? Read the decompiling FAQ and don't bother posting the question in the forums.Be sure to read and follow the forum rules. -AKA the AutoIt Reading and Comprehension Skills test.*** The PCRE (Regular Expression) ToolKit for AutoIT - (Updated Oct 20, 2011 ver:3.0.1.13) - Please update your current version before filing any bug reports.
