What are the common techniques used for code optimisation?

Some common techniques used for code optimization include:

1. Loop optimization: This involves minimizing the number of iterations or reducing the complexity of loops by eliminating unnecessary calculations or redundant code.

2. Memory optimization: This includes reducing memory usage by using data structures efficiently, minimizing memory allocations, and avoiding memory leaks.

3. Compiler optimization: Compilers often have built-in optimization techniques such as constant folding, loop unrolling, and function inlining to improve code performance.

4. Algorithmic optimization: Choosing the most efficient algorithms and data structures for a given problem can significantly improve code performance.

5. Code refactoring: Restructuring the code to make it more readable, maintainable, and efficient can lead to performance improvements.

6. Parallelization: Utilizing parallel processing techniques such as multi-threading or distributed computing can improve code performance by executing tasks simultaneously.

7. Caching: Storing frequently accessed data in memory or using caching mechanisms can reduce the need for expensive computations or disk access.

8. Profiling and benchmarking: Analyzing code performance using profiling tools and benchmarking techniques can help identify bottlenecks and areas for optimization.

9. Minimizing I/O operations: Reducing the number of input/output operations, such as file or network access, can improve code performance.

10. Code optimization for specific hardware or platforms: Tailoring code optimizations to take advantage of specific hardware features or platform capabilities can result in significant performance gains.
