Bug #: 34546
           Summary: high performance hit for wine 1.6
           Product: Wine
           Version: 1.6
          Platform: x86
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: blocker
          Priority: P2
         Component: -unknown
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]
    Classification: Unclassified

We have an win32 GUI application which

1) Iterates the mounted windows drive (some selected folder) and store it in a
list.

2) Scans the files for viruses/malware etc.

3) Show status on GUI.

Since step 1 is done initially:

So this is the loop which takes 95+% of time

while( there are files )
{
    DisplayStatus(file); -- in a separate thread not a blocking call
    ScanFile(file);
}

The performance hit is huge between wine 1.4 and wine 1.6 say atleast 5+ times
more for the same sample set.

ScanFile(file) -- It is a blocking call to a win32 dll which takes a file path
and looks for virus/malware etc and deletes/repairs a file if infected and
report the infection.
