Logging 1 Line sllError takes 15 Seconds

Hi Arnaud,

Logging on a Standard Windows 11 Computer took a long time (much longer than on my develop maschine)
After looking in the Log i found the sllError Line takes 15 second.

The only Reason i found could be the StackTrace - Routines
I set StackTraceLevel to 0 an the delay disappeared (It disabled the StackTrace Option)
as i do not need the StackTrace at this log its not important for me.

But do you have an Idea what i have to do to avoid the delay on active StackTrace ? Is there a Windows - Option ? Does the Windows User afford som special rights ?

Re: Logging 1 Line sllError takes 15 Seconds

With Win32 or Win64 executable?

Does changing StackTraceUse to stOnlyAPI or stOnlyManual change something?

Example Code

TSynLog.Family.Level := LOG_VERBOSE;
  if AppHasParam('StackTraceLevel0') then
TSynLog.Family.StackTraceLevel := 0;
  if SameText(GetAppParamValue('StackTraceUse'), 'OnlyApi') then
TSynLog.Family.StackTraceUse := stOnlyApi;
  if SameText(GetAppParamValue('StackTraceUse'), 'OnlyManual') then
TSynLog.Family.StackTraceUse := stOnlyManual;
TSynLog.Family.HighResolutionTimeStamp := true;
TSynLog.Family.LocalTimeStamp := true;
TSynLog.Family.FileExistsAction := acAppend;
TSynLog.Family.PerThreadLog := ptIdentifiedInOnFile;
TSynLog.Family.RotateFileCount := 100;    // ca. 3 Monate
TSynLog.Family.RotateFileSizeKB := 5000 * 1024;
TSynLog.Family.RotateFileDailyAtHour := 23;
TSynLog.Family.IncludeComputerNameInFileName := true;
TSynLog.Family.DestinationPath := TPath.Combine(ExtractFilePath(Application.ExeName), 'Logs');
TDirectory.CreateDirectory(TSynLog.Family.DestinationPath);
TSynLog.Add.Log(sllTrace, 'Program wurde gestartet');
TSynLog.Add.Log(sllError, 'Error1');
TSynLog.Add.Log(sllError, 'Error2');
TSynLog.Add.Log(sllError, 'Error3');

After Error 3 - Later in code

Re: Logging 1 Line sllError takes 15 Seconds

As you can see Trace=0 works as expected. The Other have Delays.
The 15s Delay is at another Place in the Program where the Stack / Memory Usage is much bigger

Re: Logging 1 Line sllError takes 15 Seconds

Perhaps the problem is that the .map file is recreated each time.

Is the .map file generated by Delphi for your project?
Is the .mab file properly generated by TDebugFile ?

Could you check if it is not TDebugFile.Create which is called by TDebugFile.Log on line 5670 of mormot.core.log which makes the delay.

Hi Arnaud,

i testet the latest commit.
Now OnlyApi is as fast as expected
OnlyManual does take the same time as before.

Hi Arnaud, i only have the EXE on the Test Machine, no map / mab file.
After starting the App i can not find a mab/map file in the folder.

Re: Logging 1 Line sllError takes 15 Seconds

I have made stOnlyApi the default settings.

Even after some fixes and refactoring, the manual parsing is sometimes incorrect.
