Thanks for reporting the issue with Forums. There is some topic in that forum that is causing token replacement to fail. Will investigate, but for now, have logged issue:
https://github.com/DNNCom...tyForums/issues/1435

For the "images" issue, that would need to be directed to the DNN platform's issues:
https://github.com/dnnsof.../Dnn.Platform/issues

BTW, I tweaked the topic that was causing this issue so you can now browse the page: https://dnncommunity.org/...ng-dnn/optimization/

thanks johnhenley :)

Hi everyone,

I recently did a fresh install of DNN 10 and noticed that out of the box, images are being served in full resolution without any optimization.

When I run performance audits (Lighthouse/PageSpeed), I’m getting a Largest Contentful Paint (LCP) value of 13+ seconds, which is marked as poor. The culprit seems to be full-size images being loaded immediately, even when scaled down visually on the page.

 Performance and Optimization Broken on DNN site

I guess you are new ot DNN?
DNN does not do any sever side scaling of images by default.
There are options but those depend on the used module(s).
Structured content modules like OpenContent and 2SXC allow you to do add this kind of control.

 

 

 

It would help to have more cintext on your benchmarking. Is this a blank page? Is this the home page of a fresh install? Or are there other modules on the page you are benchmarking? Which image is triggering this score? What is the environment? Etc.
