+Doctrine is quite big framework and usually dozens of files are being included on each request.
+This brings a lot of overhead. In fact these file operations are as time consuming as sending multiple queries to database server.
+The clean separation of class per file works well in developing environment, however when project
+goes commercial distribution the speed overcomes the clean separation of class per file -convention.
+
+Doctrine offers method called compile() to solve this issue. The compile method makes a single file of most used
+Doctrine components which can then be included on top of your script. By default the file is created into Doctrine root by the name
+Doctrine.compiled.php.
