Chandler Carruth 在 CppCon 2014 上的标杆演讲，阐释了写出高性能 C++ 的核心：在现代硬件架构下，数据结构选型与内存布局的影响力远胜精巧算法，并直击 unordered_map 等标准容器性能低下的硬件根源。
为什么 HN 推它
性能优化领域的常青必看指南。社区每当深入探讨哈希表实现、CPU 缓存行为或 STL 容器陷阱时，这篇演讲总会被奉为标准参考。
「我也是 Chandler Carruth 在 CppCon 2014 那场《算法保效率，数据结构拼性能》演讲的忠实拥趸。」HN 网友原话：I'm also a big fan of "Efficiency with Algorithms, Performance with Data Structures" by Chandler Carruth at CppCon 2014.
英文原摘要（HackerTube / Claude 整理）
Chandler Carruth's CppCon 2014 talk on writing fast C++, explaining why data structure choice and memory layout matter more than clever algorithms. It covers why standard containers like unordered_map perform poorly on modern CPUs.
A perennial recommendation for anyone learning performance optimization, cited whenever hash tables, cache behavior or STL containers come up.

See the great talk on CppCon 2014 about those issues
Chandler Carruth's CPPCon talk [0] this year was also great
I've just watched a couple cppcon talks ([0], [1]) and I'm feeling a bit drunk on the kool-aid.
Talk on STL data structures and why unordered_map uses buckets
