Significantly slower performance after upgrading to 19.7

We use Aspose.Email for .NET to extract text and metadata from emails contained in PST files.

When we upgraded from 18.4 to 19.7 we observed that the performance (of extracting text and metadata from emails contained in PST files) decreased by approximately 30 - 50%.

Is this a known issue and if so, is there a fix or workaround that we can make use of?

Thanks
