Aggressive Inlining in C# is insane

Summary

The transcript discusses the performance optimization technique of method inlining in programming, focusing on how the Just-In-Time (JIT) compiler can replace method calls with their actual body to reduce overhead. The speaker explains that small methods are often automatically inlined, but sometimes developers need to provide hints to the compiler to encourage inlining, especially in performance-critical scenarios like math-heavy loops. While inlining can improve performance, the key takeaway is to use it judiciously, as inlining large methods can negatively impact both performance and code size.
