Hi, Thanks for your interest. I know that hasNext() executes the query. When I debug, I see that only one http request is sent to the sparql endpoint. Then, I think the first result should take long time if there is only one http request. However, it takes long time to get all results, but not

Hi, When I reduce FILTER block, the execution time of the query longs shorter, but I receive less result than original query. So result set is reducing too. I recorded each elapsed time round the while loop, and there is variability at some looping times. The code that records times:
