Atlassian OnDemand products are too slow

Just wanted to let you guys know if you are considering using it. We are still using all of the OnDemand tools on a daily basis and our frustration is growing. There have been threads about the issue open for more than a year and we opened a support ticket, but it got closed with a link to an issue that is being looked into by a developer. Looking at ‘developer tools’ shows that Atlassian are generating a huge javascript and stylesheet which is taking up all the time - which they claim only happens the first time, but this seems to be causing slow page-loads (10-30sec+) periodically throughout their OnDemand suite - which is very frustrating when trying to use their Wiki system (Confluence) or browsing tickets in Jira.

If we would start from scratch, I would just go for something more lightweight like Google Docs, Trello and perhaps Workflowy.
