    41421. Now although many SPARQL endpoints support SPARQL 1.1 query, they can not take place of federated query engines.

    42442. FedX shows good performance both on its ease of use and better response.

    43463. All of these systems could finish a light query. 
     47 
    44484. Neither FedX nor ADERIS needs a pre-computed statistics information, which make them easy to use. However ADERIS queries the predicate information of all the endpoints on-the-fly query produce a big cost.

    45505. SPLENDID shows better performance except FedX , and need pre-computed predicates and other statistic information. 
    4651ANAPSID is the only one who use the non-java platform. It shows a little weakness on parsing a query, which make its performance can not be well  measured.
