Hi Andreas,The rdf/xml is just sparql describe , whereas html page render all labels as well and thus has more data to retrieve. There is also a recent fix in Virtuoso to speed to loading of labels and html text with the /describe page, but is not in the open source archive but will be soon.
Andreas,The HTML page is also providing faceted exploration which includes paging etc.. It simply isn't the same document as what's returned re. RDF/XML, Turtle etc..

However the same request and expecting an application/rdf+xml document is very fast.For instance, the following request takes more than 1 minutetime curl -i -L -H "Accept: text/html" http://localhost:8890/describe/?url=http://dbpedia.org/resource/Madridwhile the next request takes only 5 secondstime curl -i -L -H "Accept: application/rdf+xml" http://localhost:8890/describe/?url=http://dbpedia.org/resource/MadridThis makes me think that the problem is in the configuration of the http server or in the service transforming the rdf data into html. However I have no clue about which parameters should be modified.Does anyone know how I can solve this issue?Setup: Virtuoso 7, Linux - ubuntu (virtual machine with 9GB ram and 8 cpus, virtuoso buffers defined according to the ram size), around 75 million triples, fct vad installed.------------------------------------------------------------------------------ October Webinars: Code for Performance Free Intel webinars can help you accelerate application performance.Explore tips for MPI, OpenMP, advanced profiling, and more.
