A question that we receive often in the Plaza is one related to the System RAM Status on the user dashboards. Everyone wants to know… Why is it so damn high!?!
Well, the answer is more simple and easy to imagine than you may think. Here’s a real quick explanation.
The short and sweet version is: It’s completely normal.
The longer version is: Pay attention to ‘Real Memory‘ as the Cached Memory and Physical Memory are normal to show as high usage. They are only a reflection of the actual memory usage. Real Memory is the actual amount of memory being used on your system. You’ll even notice this on the widget showcase on our very own home page.
You’ll notice there is also a ‘Clear Memory Cache‘ button in the bottom right corner of the widget. This does nothing more than clear out the temporary stored memory. Under most use-cases, there is no need to flush your cached memory unless you notice that your swap is filling up fast, as cached values will roll over to swap. This keeps things speedier on your system as it is remembering past values to be able to access functions on various applications faster. It’s like your short term memory and remembering your car keys before leaving the house.
