EF Core Performance Fundamentals

Entity Framework Core is powerful but can be slow if not used properly. Let's explore optimization techniques.

1. Use AsNoTracking()

For read-only queries, disable change tracking:

var posts = context.Posts.AsNoTracking().ToList();

2. Avoid N+1 Queries

Use Include() for related data:

var posts = context.Posts
    .Include(p => p.Author)
    .ToList();

3. Project Only What You Need

var titles = context.Posts
    .Select(p => new { p.Id, p.Title })
    .ToList();

4. Use Compiled Queries

Pre-compile frequently used queries for better performance.

Conclusion

Small optimizations add up. Always profile your queries!
