大家好，相信大家在开发中经常会遇到一些性能问题，苦于没有有效的工具去发现性能瓶颈，或者是发现瓶颈以后不知道该如何优化。之前一直有读者朋友询问有没有技术交流群，但是由于各种原因一直都没创建，现在很高兴的在这里宣布，我创建了一个专门交流.NET性能优化经验的群组，主题包括但不限于：
Hello everyone, I believe many of you often encounter performance issues during development and struggle with the lack of effective tools to identify performance bottlenecks, or you may not know how to optimize once the bottlenecks are found. Previously, some readers have inquired about the existence of a technical exchange group, but for various reasons, one had not been created until now. I am pleased to announce that I have created a group dedicated to exchanging experience in .NET performance optimization. The topics include, but are not limited to:
- 如何找到.NET性能瓶颈，如使用APM、dotnet tools等工具
- .NET框架底层原理的实现，如垃圾回收器、JIT等等
- 如何编写高性能的.NET代码，哪些地方存在性能陷阱
- How to identify .NET performance bottlenecks, such as using APM, dotnet tools, and other tools.
- The implementation of underlying principles in the .NET framework, such as garbage collection, JIT, and so on.
- How to write high-performance .NET code and where potential performance pitfalls lie.
目前我们有三个微信群，两个QQ群还有1个QQ频道，总计人数约2700人，大家可以在这里面交流和讨论各种.NET新技术遇到的问题，行业内动态等等，欢迎您的加入~
Currently, we have three WeChat groups, two QQ groups, and one QQ channel, with a total of about 2700 members. Everyone is welcome to exchange and discuss various issues encountered with new .NET technologies, industry trends, and so on. We look forward to your joining us!
