Fast C++: Data Structures, Algorithms and Memory Layout

CppCon · Talk · YouTube title: CppCon 2014: Chandler Carruth "Efficiency with Algorithms, Performance with Data Structures"

Why it's here

A perennial recommendation for anyone learning performance optimization, cited whenever hash tables, cache behavior or STL containers come up.

What it covers

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.
