Thanks! Sorry, but I don’t have the chart bigger — it’s a screenshot from iStat Menus. The graphs jump around a bit, so I think the finer details may not be important. It’s more about which parts of the system are being stressed by common UI design actions on large documents. We don’t have a release date for Skala, but we’re working really hard on getting everything done. Hopefully we’ll have more to share soon. :D
