剖析线程同步锁争 [英] Profiling thread sync lock contention

问题描述

在过去，我已经使用性能分析工具，如nprof，Equatec探查和Yourkit分析器可以识别并消除/降低性能瓶颈code主要是在一个线程（串行执行）运行。现在我写了很多的多线程code可以通过锁争用减慢;什么样的工具和技巧，可以用来识别锁争正在发生以及影响有多大？

In the past I've used performance profiling tools such as nprof, Equatec profiler and Yourkit profiler to identify and remove/reduce performance bottlenecks in code mostly running in one thread (serialized execution). Nowadays I write a lot of multi-threaded code which can be slowed down by lock contention; what tools and tricks can be used to identify where lock contention is occuring and by how much?

推荐答案

这是面世不久，目前航运在Visual Studio 2010测试版2，这里是一个<一href="http://channel9.msdn.com/shows/Going+Deep/Visualizing-Concurrency-Inside-the-Concurrency-Visualizer-Profiling-Tool/"相对=nofollow>工具视频。

This is available soon, currently shipping in Visual Studio 2010 beta 2. Here's a video of the tool.
