Yes, we are running smokeping tests for few days, for a small dataset (~ 300 compounds) the response time dropped 5-6 times times, for a much bigger one with 6500 compounds it's not so drastic - only twice, but then the file itself is quite large. There is now (an experimental) parameter ?rdfwriter=jena or ?rdfwriter=stax for dataset queries on both servers, so you could try measuring as well. > >> This affects currently only serialization of >> ot:Datasets, other resources still use Jena writer. > > I'll try with Bioclipse now...
