---------------------------------------------
Hi Fabian
This is related to the "testPerformance" unit test. I had already considered to
deactivate this test because performance testing is not important to be done
during unit test. However this test does also very nicely validate that the the
filtered iterators returned by the IndexedGraph implementation return the same
triples as the SimpleMGraph implementation used as a reference.
Such tests are also included in the default test set provided by Clerezza, but
in this case they are performed on a very small set of triples and therefore
may parse by accident. This tests uses currently a Graph with 100k triples and
a randomly generated set of iterations what makes it very unlikely to miss
issues in the implementation of the Comparators used for the internal indexes.
Because of that I suggest that you adapt the following parameters of the
"testPerformance" until you reach an acceptable execution time:
int iterations = 1000;
int graphsize = 100000;
[..]
TestCase testCase = new TestCase(sg, 100, 5, 100);
You can safely change all parameters. However I would not reduce the third
parameter ('5') to TestCase.

> The test org.apache.stanbol.commons.indexedgraph.IndexedGraphTest takes too
> much time (1062ms on my machine). This is in conflict with the goal that unit

> seems that this is more a performance than a unit test.
> This test should be moved to the integration tests.
