<p>Browsers which are required to display a large amount of constantly changing real-time information tend to make excessive demands on available computational resources, since the browser needs to update the screen every time a piece of information in its document object model changes and this process is inherently inefficient. By queuing real-time data updates and emptying the queue at periodic intervals, all updates received within those intervals are simultaneously written to the browser's document object model, so reducing the burden of updating the screen. In addition, earlier updates held in the queue can be overwritten by subsequent updates, so that out-of-date information is never provided to the browser.</p> |
