Describe the bug
According to a performance analysis run on sandbox.dspace.org via Google Lighthouse, DSpace only scores 70 out of 100 points. This behavior can also be reproduced on demo.dspace.org and our own institutional DSpace instance. Therefore the performance was already mediocre in DSpace 9 and the reason for the poor performance is not the underlying sandbox server.
Google Lighthouse has several tips on how to resolve this, e.g. reducing unused JavaScript and CSS and avoid chaining critical requests. Please see the attached Lighthouse document for more information and tips.
I am not sure how easy it is to tackle this, nevertheless we wanted to run some performance analysis test during testathon, that's where this bug ticket comes from.
To Reproduce
Steps to reproduce the behavior:
Expected behavior
DSpace should perform well in a performance analysis.
Side notes
DSpace performs well in the accessibility part of the Lighthouse test 🎉 Please ignore the SEO part, the poor ranking stems from the applied robots.txt on the sandbox server.
