Why do IFrames load serially in Oracle Utilities Meter Data Management / Oracle Utilities Application Framework?
When analyzing performance of the GUI load times, we have seen that for a given portal page (e.g. 360 View - Measuring Component) each of the zones are contained within an iFrame. NOTE: The same is true for other pages within MDM, but 360 Measuring Component was the example we used. When the page loads, each of these iFrames load serially, meaning the 2nd iFrame waits to load until the first is done, and so on for all iFrames on the page. This means that the page load is only as fast as the cumulative time it takes for all iframes to load, as they are not concurrent.
