We have made some performance optimizations. Now we cache the generated reports so that we can show them to you quickly.
We are generating the reports at regular interval in the background so that the reports you see on your Dashboard are as latest as possible.
The date at which the reports were last updated is shown above the module list in the dashboard. If you want the very latest set of data, you may press the new "Update" button above the module list.
The actuall update process takes a while, but we are working on improving the same.
So overall experience of seeing the reports in Dashboard is much faster now.
Please have a look at the dashboard at http://als.adobe.com/ALSDashboard/main.html
