大家好，相信大家在開發中經常會遇到一些性能問題，苦於沒有有效的工具去發現性能瓶頸，或者是發現瓶頸以後不知道該如何優化。之前一直有讀者朋友詢問有沒有技術交流羣，但是由於各種原因一直都沒創建，現在很高興的在這裏宣佈，我創建了一個專門交流.NET性能優化經驗的羣組，主題包括但不限於：
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性能瓶頸，如使用APM、dotnet tools等工具
- .NET框架底層原理的實現，如垃圾回收器、JIT等等
- 如何編寫高性能的.NET代碼，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.
目前我們有三個微信羣，兩個QQ羣還有1個QQ頻道，總計人數約2700人，大家可以在這裏面交流和討論各種.NET新技術遇到的問題，行業內動態等等，歡迎您的加入~
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!
