Our team is developing an educational website using Asp.net webforms. We designed DAL & BAL classes and now I have some Questions:

1. Are DAL & BAL designed good ?

2. Would it be better using ORM ( like EF ) instead of using our own classes  ?(ORM are Slow ( not sure ) )

3. Should we ignore BAL and only have DAL ( 2 layer instead of 3 layer )  ?

notice that  :

• there are many users and hits.
• every page needs Database and there are many queries.
• performance and speed are important for our team.
