Original: Gallery of Processor Cache Effects

Igor Ostrovsky's classic article illustrating processor cache effects through short C# benchmark experiments is drawing renewed attention from programmers. The piece demonstrates how cache lines, cache levels and memory access patterns dramatically affect performance, with examples showing large timing differences from seemingly minor code changes. Developers are revisiting it as a practical, hands-on introduction to why memory locality matters when writing fast software.

Why now: A well-known technical article on CPU cache behavior is circulating again among programmers interested in performance optimization.
