+Known issues
+------------
+
+- There is a serious performance problem when reading camera features using the aravis library.
+  This problem is documented in an `issue in ADGenICam on Github <https://github.com/areaDetector/ADGenICam/issues/1>`_
+  The time to read all camera features on an FLIR Oryx camera using their Spinnaker SDK is 0.056 s, while it takes 11.8 s with aravis.
+  The problem is that aravis is not caching register values as it should.
+  An `issue has been created for this in the aravis repository on Github <https://github.com/AravisProject/aravis/issues/253>`_. 
+  This is a serious problem because the ADGenICam base class reads the
+  value of all features when the value of any feature is changed.
+  This means that it takes 11.8 seconds each time any feature is changed on the Oryx, for example, which is not acceptable.
+  Hopefully this problem with aravis will be fixed soon.
