sparql 1.4 billion triples

[y***@zju.edu.cn]

Dear jena,
I have built a graph with 1.4 billion triples and store it as a data set in TDB through Fuseki upload system.
Now, I try to make some sparql search, the speed is very slow.

For example, when I make the sqarql in Fuseki in the following, it takes 50 seconds.
How can I improve the speed?


Best wishes!
