How can we find performance issues in any C++ application running on Windows using profiler?
What are the free performance profilers available?

推荐答案

我从来没有找到一个非常好的免费软件，仅仅是因为一个好的软件值得它.金的重量

我亲自使用了Glowcode http://www.glowcode.com/ [ http://software.intel.com/zh-cn/articles/intel-vtune-amplifier-xe/ [

I haven''t ever found a free one that was much good, simply because a good one is worth it''s weight in gold

I''ve personally used Glowcode http://www.glowcode.com/[^] and Intel''s VTune http://software.intel.com/en-us/articles/intel-vtune-amplifier-xe/[^] and would recommend them both

In my experience, efficient code, like secure code, is normally impractical to retrofit

正如其他人所说，真正好的代码并不是免费的.但是，大多数商业分析器都提供试用期.因此，也许您可​​以在试用期到期之前进行分析.

As others have said, the really good ones are not free. However, most commercial profilers offer a trial period. So maybe you can do your profiling before the trial period expires.

如Pete所建议-您应该始终从google开始.但对于您而言，维基百科还可以提供有用的可用工具列表:

As Pete suggested - you should always start with google. But in your case wikipedia can also provide a helpfull list of available tools:
