Difference between sizes

I was wondering, is there any difference in performance if I use cubes with 10 of scale instead of 1? I made them bigger to avoid some collision problems and I resized the came to match the new size of the elements so on screen nothing changes. Could it decrease the performances?
Thank you

No, scaling an object shouldn’t affect performance.

For future reference, use the Profiler to determine performance impacts of stuff: Unity Connect
