Hi, I’m evaluating GroupDocs.Watermark .NET APIs for my company,
I noticed that adding watermarks to docx, xlsx, pptx files are very slow,
it takes about 20 seconds to add watermarks to a 20 pages 1.02MB pptx file.
I did a simple profile, it seems GroupDocs.Watermark.Watermarker.ctor() is the bottleneck:

- Is this normal?
- Is this because I’m using a trial version of the GroupDocs.Watermark product?
- What can I do to improve the performance of adding watermarks?
