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

What are the [performance improvements](https://www.mindstick.com/forum/158613/what-are-the-performance-improvements-in-dot-net-core-compared-to-the-dot-net-framework) in .NET Core compared to [previous versions](https://www.mindstick.com/forum/157962/what-is-bootstrap-5-and-how-does-it-differ-from-previous-versions-of-bootstrap)?\

.NET Core has been designed with performance in mind, and it has seen significant performance [improvements](https://www.mindstick.com/blog/306937/claude-4-explained-features-improvements-and-use-cases) over [previous](https://yourviews.mindstick.com/view/81421/unlock-2-0-is-just-like-previous-corona-lockdowns) [versions](https://answers.mindstick.com/qa/49863/list-the-versions-of-mac-os-x) of .NET. Some of the key performance improvements in .NET Core include:

- **A smaller runtime:** The .NET Core runtime is much smaller than the .NET Framework runtime, which means that it takes up less memory and can start up faster.
- **A more efficient garbage collector:** The garbage collector in .NET Core is more efficient than the garbage collector in the .NET Framework, which means that it can free up memory more quickly and prevent memory leaks.
- **Optimized code generation:** The code generation in .NET Core is optimized for performance, which means that it can generate code that runs faster.
- **Improved threading support:** .NET Core has improved threading support, which can improve the performance of multithreaded applications.
- **Support for native code:** .NET Core can run native code, which can improve the performance of applications that use native code libraries.

As a result of these performance improvements, .NET Core applications can often run faster than equivalent .NET Framework applications. In some cases, the performance improvements can be significant. For example, a benchmark by Microsoft showed that a .NET Core web application could run up to 40% faster than a .NET Framework web application.

Overall, .NET Core is a powerful and performant platform that can be used to build high-performance applications. If you are looking for a platform that can deliver high performance, .NET Core is a great option to consider.
