推荐理由
The first one is really good if you've never benchmarked anything in a Linux environment.

说明
这是2015年由CppCon发布的一部演讲，主题归在Software performance & optimization。它讲的是c++ performance tuning这一支里的具体问题，而不是把整个领域扫一遍。适合想看推导、证明或实现细节的人。内容上可以概括成：Chandler Carruth walks through tuning C++ performance, from writing benchmarks to analyzing results on real CPUs and compilers. It focuses on small-scale problems such as loop kernels, data structures and algorithms, and on keeping compilers from optimizing benchmarks away.这些读者给出的理由，核心是：HN recommends it as an eye-opening primer on benchmarking and performance analysis, especially for people who have not benchmarked on Linux.讲法不绑某一条新闻，过几年仍然可以当材料看。从2015年到2020年，有3位不同的读者在3个不同月份把它推荐出来，其中明确叫别人去看的有1次。适合一次性看完。讲者把一个判断讲透，演示是在给这个判断配例子。如果已经会了基本定义，就把注意力放在它怎么把c++ performance tuning变成能跟着复述的例子。
