I noticed when looking at the Server.Assembly table it contains both .dll and .pdb files.  This is because a decision was taken historically to compile in DEBUG mode in Visual Studio and deploy this version to the server.  Is there any advantage to releasing the DEBUG version of the code in K2, is there anything that no longer works if the code is put in RELEASE build.

From what I understand K2 retrieves the binary stream from the Server.Assembly table and writes it too disk when the process is first instantiated.  I guess if the PDB is also there it will write this to disk also slowing things down a little?
