CPU cache

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.

Igor Ostrovsky's article 'Gallery of Processor Cache Effects' is circulating again among developers and hardware enthusiasts. The piece uses small C# experiments to demonstrate how CPU cache lines, cache levels and memory access patterns dramatically affect program performance. It remains a popular reference for anyone learning computer architecture or trying to write faster low-level code.
