so select * from Song was 0.8 sec.
but in code the same query:

If the fetch takes nearly 17s instead of 0.8s there must be something wrong (or at least different). What is the exact SQL that is sent to the db, you should look at that, perhaps something in your model is wrong?

Your fetch is taking too long. What is the SQL that is sent to your db? How big is the resultset you are expecting? Perhaps your indexes are broken (you have indexes, don't you)?
