Hi ratherbefuddled,
Thank you for the insight. We are definitely working on generalized efforts to make 'most/all/everything' faster (including speeding up the app overhead), but those types of projects unsurprisingly take a little longer to finish.
On the other hand, specific user feedback might be 'the most annoying thing to me is that pages with Links load slowly, I need the links to load earlier because of X', or 'I need inline comments to load faster than page comments, because of reason Y'
-> this type of feedback could give us something we can fix quickly and alleviate user frustration sooner. Hopefully the intention makes sense.
Of course, in general, we're also always looking for any feedback that can help us improve Confluence!
