Performance testing

One of the more recent questions was: how many overhead does OCCI add with regards to performance. The following diagram shows the ‘Requests per Second’ as well as the ‘Time per request’ from one of the python based OCCI implementations. Measured where only the times is took for an OCCI framework to parse and deal with a request to show that OCCI barely adds to the performance of the overall system. As the concurrency level rises the peak number of request can easily reach 4000 request per second whereas the time per request varies from 0.2 to 0.3 milliseconds.
