We use the cloud version, I've edited huge Confluence pages and it's typically very snappy. Jira likewise. Could be an under-resourced on-premise deployment?
I think they’re talking about the front-end, not the server. FWIW both Confluence and Jira are abysmally slow on my machine (new MBP) on the cloud version.
I have seen on premise issues , infrastructure can be the problem, or config. Jira cloud can also be a problem,but nothing one can do about it other than sending a ticket. I think they know what they are doing wrong with certain "low value" subscriptions.
I use the cloud version also. While Jira doesn't have any issues, editing Confluence pages can be a right pain. It is constantly "losing my connection" and prevents editing until it's happy again. There's no connection issues present, unless they're at Atlassian's end.
Watching the network tab, all I see is a requests to `bayeux-sync1` endpoint that take 5 seconds or longer. There's always one of these requests hung when it enters this unresponsive mode. I suspect this is some part of the syncing system for multiple editors. Which, if true, makes it particularly hilarious to me that the entire point of this system would be to sync multiple edits, yet it won't let me keep editing while it's waiting...
