How to write fast Java code:

1. Basics: primitives and arrays
2. Efficient CPU Cache Utilization MatrixMultiplication.java
   • Access elements in a row-major order (sequentially in memory) instead of in column-major order (non-sequentially in memory)
3. Efficient multithreading
4. Vectorised instructions
