博客给出了一些.NET代码性能优化建议，包括预先设置ArrayLists/Hashtables大小，从一开始就在代码库中构建检测工具，重构前分析理解问题，控制日志记录量，注意.NET Remoting调用成本，以及使用PerfMon计数器等。

Pre-size ArrayLists/Hashtables etc, the performance/memory impact of not doing this is massive if you are working with lists/tables/queues that have 1000's of items
Build instrumentation into the codebase from the outset - you'll need it later for performance critical applications
Analysis and understand the problem before you refactor/re-code
Don't log too little or too much. Logging takes time. The TextWriterTraceListener classes are not thread safe. Adding a queue in front of the TextWriterTraceListener moves you into the area of point 1 above.
.NET Remoting calls are expensive - the call and the serialization. Chunky not chatty.
Use the PerfMon counters
