# What are the performance improvements in .NET Core compared to the .NET Framework?

What are the [performance improvements](https://www.mindstick.com/forum/158859/what-are-the-performance-improvements-in-dot-net-core-compared-to-previous-versions) in .NET Core compared to the .NET [Framework](https://www.mindstick.com/forum/34615/software-framework-vs-library)?

There are many performance [improvements](https://www.mindstick.com/blog/306937/claude-4-explained-features-improvements-and-use-cases) in .NET Core compared to the .NET Framework. Some of the most significant improvements include:

- **A smaller runtime.** The .NET Core runtime is significantly smaller than the .NET Framework runtime, which means that it takes up less space on disk and in memory. This can lead to improved performance, especially on devices with limited resources.
- **A more efficient garbage collector.** The .NET Core garbage collector is more efficient than the .NET Framework garbage collector. This means that it can free up memory more quickly, which can lead to improved performance.
- **Better support for asynchronous programming.** .NET Core has better support for asynchronous programming than the .NET Framework. This can lead to improved performance for applications that make heavy use of asynchronous operations.
- **Improved SIMD support.** .NET Core has improved support for SIMD instructions. This can lead to improved performance for applications that make use of SIMD instructions.
- **Improved memory management.** .NET Core has improved memory management. This can lead to improved performance for applications that make heavy use of memory.

In addition to these performance improvements, .NET Core also offers a number of other advantages over the .NET Framework, such as:

- **A smaller deployment footprint.** .NET Core applications can be deployed in a smaller size than .NET Framework applications. This can make it easier to deploy .NET Core applications to cloud-based services.
- **A more modular architecture.** .NET Core is a more modular architecture than the .NET Framework. This makes it easier to build and deploy .NET Core applications, and it also makes it easier to customize .NET Core applications.
- **A more open platform.** .NET Core is a more open platform than the .NET Framework. This makes it easier for developers to contribute to the .NET Core platform, and it also makes it easier for developers to use .NET Core on a wider range of devices.

Overall, .NET Core offers a number of performance and other advantages over the .NET Framework. If you are looking for a high-performance, modular, and open platform for developing applications, then .NET Core is a great option.
