I have to use their jira cloud offering because of my workplace. I'd already be happy if it didn't need 5 seconds to load even essentially empty pages. It's painful.
We're constantly working hard to make performance improvements on different fronts.
The new 'next-gen' projects are more performant due to a tech stack update - the interactions and are snappier and updates are near realtime. Come check it out by creating a new 'next-gen' project in your Jira Cloud instance.
Outside of 'next-gen' projects, we're currently working on general performance improvements that will benefit all users.
We're currently making transitions between different parts of the product a lot faster through data pre-load and pre-render techniques. We're also working on optimising the front-end and back-end calls for faster loadtimes in general. We're looking at investing in more datacenters to keep lag times down for you.
Please keep a lookout on performance improvements. It might be hard to notice this day to day, but we have been and are always investing on this.
With age we've incurred some technical debt but rest assured we are unwrangling the complexity everyday so we could optimise our software for you.
