Restrictions of demo licences

I evaluate pdf js express plus, (without license key) but I notice that viewer has a different behaviour that your demo page. Such as the documents are rendering slowly. I notice also pdfjs express watermark on document locally.
Did can be because I evaluate without license key?

Hi @user45,

The watermark on localhost will persist regardless of a valid license key. A valid key in production will remove the watermark.

As for the documents there should be no difference. Could you provide one of the documents you are noticing slowness on?
