Why is Runtime Broker consuming so much memory

After upgrading from Windows 7 Ultimate to Windows 8 Pro, I began downloading Apps from the Store.  After several days of using (and enjoying) Windows 8, I noticed that memory usage was getting pretty high and that Runtime Broker was consuming a lot of memory.  I found out the root cause in my specific case and am posting it here hoping my findings would help others.  To make a long story short, the problem was a bad App called The Time.

I uninstalled all the Apps I had previously downloaded and re-installed them one-by-one.  Each time, I jotted down the following:

Why is Runtime Broker consuming too much memory?

Hypothesis: Appears to be a badly written App.

10/31/2012 8:58am

Runtime Broker memory consumed is 19.5MB then went to 19.1MB

11/1/2012 12:13am

memory used by Runtime Broker is consistently in the range of 19.6-19.7MB

11/1/2012 12:14am

installed The Time (the one created by Jeff Key).  Runtime Broker memory consumed is 19.7MB

11/1/2012 12:17am

Runtime Broker memory consumed is 20.7MB

11/1/2012 12:31am

Runtime Broker memory consumed is 59.3MB <— increasing 40MB per 15 minutes

As you can see, it was only after I installed The Time by Jeff Key did Runtime Broker memory usage begin to increase significantly.  Although the snapshot from 12:17a.m. to 12:31 a.m. was only for 14 minutes, it is showing an increase of roughly 40 MB per 15 minutes.  After 8 hours, (8 hrs x (60min/hr)  x (40MB/15min) =1280MB (or 1.2GB) will be consumed. After 16 hours, 2.4GB will be consumed. It is a symptom that The Time app has a memory leak. Any application, especially this kind, should not be doing that and will begin to slow your computer down.

To recover from this, I had to uninstall the application and restart the computer.  I needed to restart the computer to get my memory usage back to normal levels.  If I didn’t restart, the leaked memory is never recovered.

Good luck to you and I’m glad to be of help to you and whoever else is out there.
