How do you optimize EF Core performance for large datasets?

Updated Apr 28, 2026

Short answer

Optimization requires efficient querying, minimal tracking, index utilization, and batching operations.

Deep explanation

Strategies include: 1. Use AsNoTracking() for read-only queries. 2. Project only necessary columns using .Select(). 3. Use Pagination (Skip/Take). 4. Use Bulk Extensions (ExecuteUpdate/ExecuteDelete in EF Core 7+) to avoid loading entities into memory. 5. Optimize the LINQ translation to ensure proper index usage. 6. Avoid N+1 queries using SplitQueries or eager loading.
