测量C ++中的异常处理开销

问题描述

请提供独立的代码示例。

我的目标是Microsoft Visual C ++ 2008和gcc。

我需要从以下情况得到结果：

1. 没有try / catch块时的开销


2. 有try / catch块但是没有抛出异常的开销


3. 抛出异常时的开销

解决方案

完全专注于例外。

What is the best way to measure exception handling overhead/performance in C++?

Please give standalone code samples.

I'm targeting Microsoft Visual C++ 2008 and gcc.

I need to get results from the following cases:

1. Overhead when there are no try/catch blocks
2. Overhead when there are try/catch blocks but exceptions are not thrown
3. Overhead when exceptions are thrown

解决方案

Section 5.4 of the draft Technical Report on C++ Performance is entirely devoted to the overhead of exceptions.
