How does the size of an array affect iteration performance?

The size of an array can significantly impact iteration performance due to factors like cache efficiency and memory access patterns.

Can you explain how cache efficiency plays a role in this?

Certainly! Larger arrays may lead to cache misses, which slow down performance as the CPU has to fetch data from slower memory.

Are there any specific examples or benchmarks that illustrate this?

Yes, benchmarks often show that iterating over smaller arrays can be faster due to better cache utilization compared to larger arrays.

What strategies can I use to optimize iteration over large arrays?

You can optimize by using techniques like loop unrolling, blocking, or even parallel processing to improve performance.
