It looks pretty standard ... it does have GitHub integration enabled, and custom fields and workflow for each project, which seems like a pretty standard thing for organizations/users to do.

But my key anecdote is about loading the notifications sidebar after the page has loaded, there shouldn't be any customizations in there. But I dunno, maybe Jira gives managers a bit too much rope with which to hang their development teams.

And this level of open-ended configurability is why many vendors prohibit benchmarking. While Atlassian is exceptional in some regards, this is not one of them.

If jira is slow crap when used in the way real people use it then isn't this a meaningful fact worth sharing?
