You have to figure out who is calling GetString(). Don't you have the
stack trace that points to the right place to optimize? If you don't,
just print 1 stacktrace out of every 100 calls to GetString and you'll
see who is calling ByteEncoding.GetString.

GetOrdinal() is pretty heavy creating string instances and most of them
can be avoided (name.ToUpper() and fieldName[i].ToUpper() called on
every iteration!).
