How big is the model, and what format are you writing the file in? Some formats -- for example RDF/XML-ABBREV and TURTLE -- try to write 'prettily' which requires some work to achieve the most human-readable output. If you consult the documentation [1] you'll find a list of 'pretty' formats to avoid, and faster alternatives. (N-Triples is always fast) Note that for many of these you need to move from model#write(...) to RDFDataMgr#write(...). Damian [1] <https://jena.apache.org/documentation/io/rdf-output.html>
