renderImage speed

We have a case where we render the pages of a PDF to 0.1 scale using PDFBox
2.0.4.

When it hits PDF downloadable from the following page, it takes 37 seconds
- way longer than the other pages and probably because of graphical
elements.

https://www.yorkhospitals.nhs.uk/our_services/az_of_services/physiotherapy/physiotherapy_at_york_/physiotherapy_for_womens_health/bump_physiotherapy_groups/

- On the right there's a "BUMP" PDF

I'd like to understand why PDFBox is seemingly so slow on this page since
it will likely cause delay in front of customers. Any thoughts?

Thanks,

James

Thanks for this - now takes 3-4 seconds :-)

I can render it in 3.4 seconds at 100% and my PC is a bit old.

Did you set the property mentioned here?
https://pdfbox.apache.org/2.0/getting-started.html

If I don't set the property, it takes 10 seconds for me.
