[Pellet-users] Pellet Performance Issue

[Georgios Meditskos]

I assume that after loading the ontology, you do not perform 
classification or realization.
Thus, when the first query runs, Pellet needs to realize the instances 
(ABox reasoning) for the first time. After that,
it has computed all it needs. That's why the next queries are so fast.
