Jira Cloud works really badly on my browser

Question

Jira Cloud is really slow when I access any site on any browser. It makes the browser extremely slow and it looks like it's getting stuck all the time. It looks as though the website had hundreds of thousands of software layers that interweave, producing a heavy resource load. I think Atlassian should get down to improving the performance and efficiency of the Jira Cloud website in general. It won't get better the more software and JavaScript gimmicks we add to it, quite the opposite, from my point of view for a website to be excellet quality it should be as lean and efficient as possible, offering its features with the lightest resource load as possible.

I really hope this might serve as a wake-up call for Atlassian to work on the performance of Jira Cloud.

Thanks millions.

Until yesterday I didn't know Chrome had a way to check which tabs are using up most resources (Shift + Esc), but once I did I noticed that Jira is right there on top of the list (and I usually have a lot of tabs with different crazy SaaS apps open). Then one of our users did the same and came back with the same result. Jira is a memory hog and we are only using JSM with very simple ticket functionality. I think it is time we develop our own app.

Yes, it is slow on Chrome. Intel graphics card, Intel Core i7 CPU.

Yep, whenever I start using Jira cloud at my company...
(opening card, checking dashboard, editing cards etc, adding comments, basically using Jira)

Then my laptop hits 100% CPU usage, and things run slow.
And it's Microsoft Edge, and Jira Cloud using all this CPU...

It's impressive that the Jira website / UX can use this much CPU.

I feel this amount of CPU requirement comes from large Web UI projects using frameworks like React or Angular.
