HIbernate query taking very long time

Question

I am trying optimize my code. I fetching the data using Hibernate, when I am running the query directly on the database it fetching the results in 2secs, rowcount around 2800. Same query when I fire from my Java code takes 8 secs. I have included the code snippet below.

Session hSession =openSession();
Query query = hsession.createSQLQuery(searchString); 
List results = query.list(); // it takes 7 secs to execute

I am not sure what is wrong over here.
