Why is the "Copy with Constraints" function very resource-intensive?

Hello

In Solidworks, I frequently use the "copy with constraints" function.

On small blends, it's very effective.

On the other hand, on large assemblies, this function is very greedy and therefore much slower, even if the copied part is very simple and has only 2 constraints.

Is there a setting to make this function faster?

Hello, I take the liberty of digging up the subject because I encounter the same problem...
Thank you in advance for your answers.
