Description	In our work we deal with the problem of finding an efficient ordering method for XML. We solve this problem in context of the XML-Lambda Framework, an environment for evaluation of XPath/XQuery queries using a functional type system and a query language based on the simply typed lambda calculus. Inappropriate ordering is one of the most common issues that may cause poor performance results achieved by applications updating large XML documents. Several approaches for an effective ordering already exist as a result of extensive research work up to now. We acquainted us with and implemented particularly those based on the Dewey ordering method, namely ORDPATH, Extended Dewey, and IFDewey. We carried out a number of performance benchmarks of various methods and publish the results in this contribution. In the experiment, we take in account all basic operations over XML data, i.e. document parsing and serialization, and its in-memory modifications.
