Introduction

In this section a number of varied queries submitted in the production infrastructure, along with the response times of the gCube system are recorded. The target is to evaluate the performance of the search functionality provided by D4science services.

When submitting a query from the D4science portal, the procedure that is followed until the first results are retrieved is the following:

  • The Application Support Layer constructs the query according to the SearchMaster Syntax
  • It communicates with IS, in order to retrieve the EPRs for the search master running instances
  • The query is submitted to the SearchMaster
  • SearchMaster finds and returns a ResultSet EPR
  • The results are retrieved
