In fact, i have different results using OWL_MICRO and Default configuration.
Plaese, is this natural?
Yes, MICRO is performing fewer inferences in return for better speed and
scaling. See https://jena.apache.org/documentation/inference/#OWLcoverage

To use OWL_MICRO i call this function:
ReasonerRegistry.getOWLMicroReasoner().bindSchema(schema);
To use default OWL i cal this function:
ReasonerRegistry.getOWLReasoner().bindSchema(schema);
Plaese Is this correct.

Thank you Dave, effectively the materialization of the model make the writing
in file really faster.
Thanks

The inference finished after 2 seconds. The probleme is whene i take resulted
Model to save it in a file.
If the inference uses backwards rules, it doesn't run to completion until
you force it to by
examining all the triples. So the two seconds could just be
setup and then the rest of the time could be running the backwards rules.
Indeed, it is very likely your 3-4 hours are the inference not the writing.
First, use the OWL_MICRO configuration not the default OWL configuration
(if you are not doing this already).
Second, materialize the model first before trying to write it all out:
Model result = ModelFactory.createDefaultModel();
result.add( myInferneceModel );
Then
you will see the time to do that step and can write out the result
faster.
