+Summary: Objects with multi-dimensional arrays are deserialized slower each subsequent deserialization call.
+
+Description of Problem:
+Performance issue with deserialization of mulit-dimensional arrays. With
+each subsequent call of a deserialization of an object with a
+multidimensional array (int[size, size]) each deserialization gets slower
+and slower.
+
+On my machine the first deserialization takes light-speed 0ms but with each
+further object-deserialization it gets slower and slower, after 20000
+deserializations it takes 63ms!
+
+If you create the object with a one-dimensional arrays-version
+(int[size*size]) it takes 0ms-1ms on all iterations
+
+See the attached Testcase.
+
+
+Actual Results:
+Deserialization gets slower and slower each call.
+
+Expected Results:
+Deserialization should happen at constant speed.
+
+
+How often does this happen? 
+Always.
