User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:65.0) Gecko/20100101 Firefox/65.0

Steps to reproduce:

1. opened PDF  located at: https://wiki.eclipse.org/images/0/07/CDO-Poster.pdf


Actual results:

Firefox / PDF.js takes 5minutes on rather modern hardware (I5-6300U / Windows-7) to render the PDF


Expected results:

Firefox should be at least as fast as evince (15s) loading this file.

Google Chrome loads the PDF in 2-3s.
