Ok. Thanks a lot I'll ask my manager to contact you soon then :)

Try using SPARQL.
Performance depends greatly on how the platform is configured. We can help you maximize performance for your application under our accelerator program. This program goes beyond our basic developer support program and is designed to give you access to the core development team to help you develop your application and get it ready for the market, including our support for your internal performance tuning of your application.
We do not provide these as free services. Proper benchmarking and performance tuning are a complex and time consuming activities. On the other hand, we can provide references to existing customers that have been deeply satisfied by their engagement with Systap around the bigdata platform. If you do your own performance testing, you should realize that misconfigured deployments can result in substantial bais in the test results.
Thanks,
Bryan

Sorry for a chain of mails. If SPARQL* does not make an difference to the performance than its ok I can work with SPARQL too as I have shown in my example.
