Honestly I reckon half of Jira's reputation for slowness could have come from bad on-prem installs. The cloud version is not slow, and Atlassian does do work on performance

Also no shortage of folks elsewhere in this discussion talking about cloud slowness.
We've had plenty of irritations with our on-prem, but slowness, not so much. And yeah, for us it's mostly about keeping the data internal.
There’s a ton more indirection for userids. Screens that used to be part of my standard workflow have Ajax handlers. Even name completion is slow.
The #1 question answer on the old ui survey workaround asking why are you using the old ui: slowness.
Confluence also got clobbered. I can count page load times.
I think it's more of a software problem tbh.
Overall, we are very happy with Jira and it's worth the cost for the value it brings to the organization (still hurts the wallet, but it's at least justified).
...and then Atlassian comes along and rug-pulls on-prem Jira.
We only have ~80 users, so 1000-user-minimum data center isn't going to cut it for us. And there is an on-prem requirement, so no cloud option either (wouldn't want to anyway). And for that, I bitch. Fuck Atlassian and everything they do to appease their shareholders before the customers.
