Slow PDFViewer for many-pages document.

Hi. My app is a React app on ASP.Net Core. I am using <EJ.PdfViewer serviceUrl={...} documentPath={...} to render PDF files.

The speed is ok for single page small documents. But it is too slow for many pages document. Our sample PDF is a 503KB file with 20 pages. It takes 5-7 seconds to load the first page, then when I scroll down the PDFViewer to see the next pages, it takes 5-7 seconds to load each page.

Is there anything I can do to improve the speed?

Thanks,
Nga
