I 100% agree on the speed here. I thought it was just my inability to self host Atlassian products. I tried Atlassian OnDemand and the performance was actually worse compared to self hosting.
I legitimately don’t know if I’m just bad a “tuning” their stuff, but JIRA and Confluence in particular were nothing short of miserable to use daily. Bamboo was great, but it had a lot less daily interaction than JIRA, for obvious reasons.
