1791491 - Flickr.com pages slow to load

Status: RESOLVED INACTIVE

(Core :: Performance, defect)

Description

[campbell_kerr]

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:100.0) Gecko/20100101 Firefox/100.0

Steps to reproduce:

Browse flickr, load this page:

https://www.flickr.com/photos/fico86/8925396286

Actual results:

Flickr in general seems (is?) slow and laggy for me in Firefox. Edge seems a lot more responsive.

Expected results:

Flickr is probably NOT the snappiest site in the world, but it seems much happier in Edge than FIrefox.

Hello, could you please help collect a new performance profile but add the permalink in this bug instead of the url from the browser? Otherwise we won't be able to see it unfortunately. Thank you.

Thanks, I've done a few new traces. It actually feels a bit quicker now for me. Hard to tell, but here's the links:

I see a lot of slowness here but there isn't one specific culprit that stands out.

These profiles in particular are very bad: https://share.firefox.dev/3SLKg28 and https://share.firefox.dev/3Dn5PjI was the machine particularly busy with other work during this time by any chance?
