Leonard, I believe the benchmark you were referring to is the SP2 benchmark that specifically tests SPARQL performance of triple stores. I agree with Irene: your choice of triplestore should be driven by the demands of your application and not on a single benchmark data point, because the benchmark may not be testing the features you intend to use, and the triple-store market is changing rapidly too, so benchmarks are quickly outdated. This is evidenced by the recent benchmark for AllegroGraph on the Franz website which shows a huge jump in performance over the earlier SP2 benchmarks. It is not clear from the Franz site whether the same class of server was used as the original SP2 benchmark. I have also heard that an unreleased triple store is producing high the triple numbers on the SP2 on stock hardware.
If you intend to use a lot of SPARQL in your application, I encourage you to take a look at The SP2 is really easy to use and the queries are very straightforward to understand. They tested very specific characteristics of SPARQL performance in each query and they have made it really easy to try the queries out. However remember that SP2 does not test SPARQL Update performance, inference performance, data ingest performance, or the Triple Store API, etc. Arthur On Sep 22, 2011, at 12:45 AM, Irene Polikoff wrote: > Yes, this is what I meant by “very moving market” J > > However, I am not in a position to say if this benchmark study would have > reached different conclusions if it was ran today.
