 Test case

 I forget to attach the test case which shows the problem.
 I tested this code and not "real" library implementation.

+Just replace Dictionary<string,int> in your test case's main method
+with Hashtable (and "dd.TryGetValue" by dd.Contains or dd[...]) and
+you'll see the time drop.
+For me it went from 1.4s to 0.8s.
+I'll look into it today and try to rewrite the code in Dictionary<K,V>.
