Yeah, our on-prem Atlassian installation is utter crap performance wise, opening a Confluence page often takes 30 seconds or more. I also get pissed off every time we try to upgrade our SolidWorks installation because they share a DB server. Atlassian doesn't support the most recent versions of Microsoft SQL Server, but SolidWorks only supports the latest couple revisions of Microsoft SQL Server so every time it is a pain to ensure that both systems are compatible and my IT refuses to move SolidWorks to a new server.
