I am using hibernate to update 20K products in my database.

As of now I am pulling in the 20K products, looping through them and modifying some properties and then updating the database.

so:

load products

foreach products
   session begintransaction
   productDao.MakePersistant(p);
   session commit();

As of now things are pretty slow compared to your standard jdbc, what can I do to speed things up?

I am sure I am doing something wrong here.
