內容簡介
在當今飛速發展和充滿競爭的世界中，對於客戶而言，程式的性能與功能一樣重要。這本實踐指南為開發人員講解在C++中實現最佳化的性能調優原則。你將學習如何令已經包含了C++設計實踐的代碼在任何計算機上——無論是手錶、電話、工作站、超級計算機還是全球伺服器網路——很快地運行並消耗少的資源。
作者提供了幾個運行示例，演示如何逐步套用這些原則以改進現有代碼，從而滿足客戶對回響速度和數據吞吐量的要求。

Summary
2． Computer Behavior Affecting Optimization
Lies C++ Believes About Computers
The Truth About Computers
Memory Is Slow
Memory Is Not Accessed in Bytes
Some Memory Accesses Are Slower than Others
Memory Words Have a Big End and a Little End
Memory Has Finite Capacity
Instruction Execution Is Slow
Making Decisions Is Hard for Computers
There Are Multiple Streams of Program Execution
Calling into the Operating System Is Expensive
C++ Tells Lies Too
All Statements Are Not Equally Expensive
Statements Are Not Executed in Order
Summary
3． Measure Performance

Summary
4． Optimize String Use： A Case Study
Why Strings Are a Problem
Strings Are Dynamically Allocated
Strings Are Values
Strings Do a Lot of Copying
First Attempt at Optimizing Strings
Use Mutating String Operations to Eliminate Temporaries
Reduce Reallocation by Reserving Storage
Eliminate Copying of String Arguments
Eliminate Pointer Dereference Using Iterators
Eliminate Copying of Returned String Values
Use Character Arrays Instead of Strings
