There's not really enough information to say definitively, but more than likely the first alternative (direct database queries) is probably faster. I say this because in the second alternative, you still need to query the database, but you are just adding another layer to the process, ie. the REST service layer. However, the difference is probably so small that other factors would probably outweigh these, ie. the fact that your servlet could "hide" the implementation details of the database, and/or include common business logic for managing the data in the database in the one single place.

Where the situation might be reversed though (so that the second alternative might be faster), is dependant on exactly what you might be doing with the data. For example, say you are retrieving a substantial amount of data from the database and then operating on that data. In the first situation, you need to move all that data across the network from the database to the front end and so THIS may be the bottleneck, where as in the second alternative, the data is retrieved locally and THEN operated on before sending (via REST) just the small result of those operation to the front end.

So, as you can see, a definitive answer to your question would depend on a lot of factors!
