  1. Performance analysis of three semantic web prototype applications:GORouter, AllegroGraph and YeastHub. In this table, the AllegroGraph http://www.franz.com/products/allegrograph/ project used the disk approach to query "LUBM50, Lehigh U. Benchmark" datasets (about 6.88 million triples). The retrieval speed is about 0.04 million triples per second. The YeastHub http://yeasthub.gersteinlab.org project uses the main memory approach to query the UniProt data file (about 1.4 million triples).
