The most intuitive reason is that all the temporary values for every level of recursion are stored in the memory separately, but the closure is actually updating the same variables in every loop. Also, there is a depth limitation for recursion.

WebJun 12, 2024 · Memoization can be a more powerful tool if a recursive function is called multiple times with different arguments, as its cache persists between calls, while iteration can be faster for recursive computations that are used less frequently. Always pay attention to your code and optimize for the cases you know or anticipate to be more common. WebJul 9, 2024 · Code compiled into "WVM" is usually not as fast as code compiled to "C", but as it is still somewhat on the Mathematica side, the communication with the MathKernel tends to be a bit quicker (e.g., see here ).
