The JAA spin database has become enormous, which is causing additional performance issues. This is not a programming issue, it is a limitation of the hardware and when it gets to such sizes, the only option is to split the database. But this is not so simple. If you have old data you don't use any more, please remove it. But unfortunately this is not the end solution because the database will continue to grow. Before it becomes a serious problem, work is being done on a new version of JAA from the ground up. I didn't originally anticipate so many people would be using it, all but the load on the server would be so large. The new version will incorporate the additional pattern as explained earlier, and this will mean it is even easier to use because less data is required for analysis. I'll provide more details about this closer to release date.
Again always keep your own records of your data, so that any issues with the database are not a serious problem.
