We have updated Groupdocs.Conversion to version 23.6.0 (previous version was 22.9.0) and we now see that the conversion (.msg to .pdf) takes much longer (14 to 15 seconds) than with the previous version (4 to 5 seconds).
Below is the code we are using.
// Set GroupDocs.Conversion license
new License().SetLicense("GroupDocs.Conversion.NET.lic");
// Define file paths for input .msg and output .pdf
var pathMsg = Path.Combine(Environment.CurrentDirectory, $"Data\\TESTWV.msg");
var pathPdf = Path.Combine(Environment.CurrentDirectory, $"Data\\TESTWV.pdf");
// Get possible conversions for .msg files
var possibleConversions = Converter.GetPossibleConversions(".msg");
// Disable conversion of owned emails to optimize performance
((EmailLoadOptions)possibleConversions.LoadOptions).ConvertOwned = false;
// Create a new FileStream for the output .pdf file
using (var fsPdf = new FileStream(pathPdf, FileMode.CreateNew, FileAccess.ReadWrite, FileShare.ReadWrite))
{
// Open .msg file as a document stream
using (var documentStream = File.OpenRead(pathMsg))
{
// Initialize the converter with the document stream and load options
using (var converter = new Converter(() => documentStream, () => possibleConversions.LoadOptions))
{
// Set options for PDF conversion
var options = new PdfConvertOptions();
// Perform the conversion and save the result in the FileStream
converter.Convert(() => fsPdf, options);
}
}
}
Are we doing something wrong or what could be the reason for this performance issue?

Another difference between these versions, version 22.9.0 converts images in an email and version 23.6.0 does not (see pdf attachments in previous message)!
We’re pleased to inform you that the improvement you mentioned will be included in the upcoming release, version 23.7. The expected conversion time is projected to be around 4 seconds once again. Once the release is on-board, we’ll notify you.
The issues you have found earlier (filed as CONVERSIONNET-6202) have been fixed in this update. This message was posted using Bugs notification tool by nikola.yankov
I did some tests with the new version 23.7.0, but I don’t see any improvements, 23.7.0 isn’t really that much faster than 23.6.0! The conversion from .msg to .pdf is still slow and the image conversion problem is also not fixed.
Another big difference we see between version 22.9.0 and versions 23.6.0 and 23.7.0 is that with version 22.9.0 the ‘SetLicense(…)’ takes quite a long time and almost no time for the other versions (but the conversion of these versions is much slower).
We are really sorry for the inconvenience caused. We have logged these issues for further investigation. Your investigation ticket ID is CONVERSIONNET-6233. We’ll notify you in case of any update.
