+Subject: [PATCH] Optimize DataBits
+
+Remove Debug checks as these are super hot and causing noticeable hits
+
+Before: http://i.imgur.com/nQsMzAE.png
+After: http://i.imgur.com/nJ46crB.png
+
+Optimize redundant converting of static fields into an unsigned long each call by precomputing it in ctor
