Earlier quoted context omitted.
As a first step, 1s would be better than nothing for sure, but you need to be working towards a much tighter goal on a 1-2 year timeframe. New load, you should really be hitting 200ms as your 95th percentile - 300ms or so would be decent still. "Transitions" should hit 100ms 95th, 150ms would be decent. If you did hit 100ms across the board, you'd be rewarded by your customers/users psychologically considering the in…
Thank you for coming back and clarifying. Do you happen to have links to any public testing results of other tools, or guidance to this specificity - would love to use them to build a case internally Most of what we've seen online are nowhere near this level of detail (X-ms for Y-%ile for Z-type of load) (edit: clarified request)
On what users experience as effectively "instantaneous", that's from experience on UX engineering and industry standards - https://www.nngroup.com/articles/response-times-3-important-...
On the other noted times, they're just a general range of what can be expected from a reasonably well-built tool of this nature. Obviously much simpler systems should be drastically faster, but project management tools do tend to be processing quite a bit of data and so do involve _some_ amount of inherent "weight", but that isn't an excuse for very poor perf.
That said, I imagine if your PMs do some research and go ahead and try using some of the common project management tools, you should get a good idea. ;) Keep in mind speeds to Australia (assuming Atlassian is operated mostly there?) will likely show them in a much worse light than typical perf experienced in the US/UK/EU areas.
The time to first load is derived from the fact that you're running essentially the equivalent of many "transition" type interactions, but they should be run almost entirely in parallel, so roughly 2x between "transition" and "new load" is a reasonable allowance.
