В кластер входят документы, посвященные техническим методам оптимизации кода и повышения производительности в среде .NET и языке C#.
Общие признаки: повышение быстродействия C#, низкоуровневое управление памятью и CPU, оптимизация циклов и JIT-компилятора, эффективность рекурсии в CIL
Группа выше: Производительность и память в .NET
Смысл: The text advocates for the use of tail-recursive functions over traditional loops in .NET, demonstrating that with the right language (Nemerle) and CIL instructions ('tail.'), recursion is as efficient as iteration.
The author argues that tail call optimization in .NET, particularly via Nemerle, makes recursion a superior and efficient alternative to traditional loops.
Смысл: The main idea is that manually storing array.Length in a local variable before a for-loop in C# does not provide any performance benefit because the JIT compiler optimizes both patterns to the same assembly code. Additionally, foreach loops are generally faster for arrays than for-loops because they allow the compiler to remove redundant bounds checks.
Manually caching array length in a local variable in C# provides no performance gain due to JIT optimization, while foreach is often faster than for-loops for arrays.
Смысл: The main idea is that peak performance in C# can be achieved by bypassing high-level abstractions in favor of low-level memory and CPU management, provided the developer has a deep understanding of the underlying technology.
A technical deep-dive into 30 low-level optimization techniques for C# to achieve extreme performance, proving that .NET can compete with unmanaged languages when standard abstractions are bypassed.
