If you’ve followed my previous blogs, The Cost of Garbage Collection: Understanding the Performance Impact in .NET Applications and Garbage Collection in .NET: Advanced Techniques for Better Performance you’re already well familiar with the complexities of .NET’s garbage collector. In the continuation of previous blogs, we’ll explore advanced memory management best practices that allow your .NET applications to achieve better performance by minimizing GC overhead and optimizing memory usage. This blog is designed for developers seeking expert-level insights into making their .NET applications faster and more efficient.

Understanding the GC’s Role in .NET Performance

Before we dive into best practices, it’s important to reiterate that the garbage collector in .NET is designed to manage memory allocation and reclamation automatically. It works efficiently in most scenarios, but as applications scale or require low-latency performance, the GC can become a limiting factor. By understanding how to manage memory efficiently, you can help the GC do its job with minimal interruptions to your application’s performance.
