Iguana: A Generic Framework for Benchmarking the Read-Write Performance of Triple Stores [chapter]

Felix Conrads, Jens Lehmann, Muhammad Saleem, Mohamed Morsey, Axel-Cyrille Ngonga Ngomo
2017 Lecture Notes in Computer Science  
The performance of triples stores is crucial for applications driven by RDF. Several benchmarks have been proposed that assess the performance of triple stores.  ...  We execute the FEASIBLE and DBPSB benchmarks using the Iguana framework and measure the performance of popular triple stores under updates and parallel user requests.  ...  (GA 01MD15006E) financed by the BMWI.  ...
