3. Minimize the number of data access operations.
4. Use appropriate data structures and algorithms.
5. Leverage hardware features like SIMD instructions.
6. Pre-allocate memory and minimize dynamic allocations.
7. Utilize caching, parallel optimization, and vectorization.
8. Avoid synchronization, if possible.
9. Use optimized libraries whenever possible.
10. Learn low-level optimization techniques such as LTO, ASM, and JIT.
