How Does CPU Prefetching Make Your Code Faster? (Page Coloring, TLB)

Описание: Want to optimize your code even further? This video dives into advanced techniques like CPU prefetching, where the CPU predicts future data needs, and page coloring, an OS-level optimization that manages memory layout across cache sets. We'll also explore the Translation Lookaside Buffer (TLB) and its role in speeding up memory access, showing how these Ninja-level techniques can significantly impact performance optimization.

🧠 What You’ll Learn:
✅ What is page coloring and why it exists
✅ How virtual memory pages map to cache sets
✅ What causes cache aliasing and conflict misses
✅ How page coloring improves cache efficiency
✅ Whether you can (or should) use page coloring in your own systems

💡 If you care about cache locality, system performance, and low-level memory control, this episode is for you.
