Hello,

Most of the CPU is used to show data on video. You could remove visual effects (if any), reduce the number of updates per second and so on to try to get better performance.

Please try to subscribe your NonVisualTables but remove every visual "notification" (i.e. just subscribe and use an empty NonVisualItemUpdateEvent listener). How much CPU is used?

With the NonVisualTable approach more memory is used because each item must be handled by 2 objects (the ArrayCollection and the NonVisualTable) and so some data is kept by both. The VisualTable extends the ArrayCollection and is written so there is no redundancy on data.

Moreover the Flash player uses a "step" approach to allocate memory from the system. See http://blogs.adobe.com/aharui/2007/0...nd_memory.html
