The WPE (WISDOM Production Environment) is a job management system on the grid, which is successfully used in several virtual screening projects for malaria, such as WISDOM-I (2005) and WISDOM-II (2006). The experience using WPE showed however that there are still challenges to address such as agents massively killed when the Task Manager is empty, or the status monitoring module noticeably slowing down after a long execution time. We carried out tests to measure WPE performances and compare them to DIRAC's, a similar job management system. The obtained results confirm the problems encountered. To improve WPE performances, we discuss the reasons and propose corrective plans. This paper describes the scenario and results of the performance tests for the WPE before and after the corrections.
