First query takes 4+ minutes to complete

Hi, we are evaluating ObjectDB 2.5.1_04 in embedded mode hoping to replace SQLite in our application. We observed that in our case it takes on average more than 4 minutes to complete the first SELECT query that we run on the DB which contains about 320,000 records of a single type of object.
