c# - Entity Framework 6, best strategy to get filtered data from big table with many links to other tables

Which of these ways is better:

  1. to perform 10000 small queries with filtration conditions to table linked with many other tables (we need data from linked tables too (doing .include() in LINQ expression)) or;
  2. to get the data from the table and linked tables piece by piece without any conditions (in a loop, in 10 iterations => 10 queries to db), load them in a collection and then during every iteration perform all analytical work by LINQ with collection?

I think that second way will be faster but what about memory and how to solve this problem according to the rules of clean architecture?
