So in terms of Flex 2, would it be able to possibly handle this amount of data effectively since it uses flash 8?
It sounds like you are saying that 1.5 has trouble displaying that amount of data because of ram usage problems? does that same problem exist in flex 2? Is there a max on how much memory flash player 7 is able to use effectivly? is that max much larger in flash 8.5 player? It sounds to me like it might be easier to port this thing to flex 2 than it would be to try and plug in to flash 8 bitmap features and draw my own graphs. as far as data points, well, it's 200 machines * 60 properties * 60 minutes = 720,000 data points that i need to hold in memory at any given time. I'm also being asked to update the data points at a rate of once per minute ie 200 machines * 60 properties = 12,000 updated data points per minute with an eventual goal to get those updates down to once every 10 seconds.. is that something that is doable by flex 2 even? They've got an app here written in mfc (c++) that can do it, but they'd like to have it accessible from anywhere on the web... Have there been any performance papers published on flash describing memory usage, etc?
