 When the number of triple size is less than 100M,  4Store can perform well both in loading data and query although providing only limited features. For data with moderate size such as varying from 100M to 500M or so,  Virtuoso and OwlimSE have similar or comparable performance. When increasing data to several billions, Virtuoso works best in the five test triple stores.

+In the future we will evaluate federated queries as well as the triple store's inference ability,  and try to make each triple work their best. In addition the query use cases  we used in  this study  are designed mainly based on their daily usage, which includes long join operations as long as 10, kinds of filter operations, and  almost all the clauses frequently used in the Sparql queries. Some other use cases can be designed aiming to test the  detailed performance of each triple store, such as test on PSO,POS indices and so on.
