Composite Definitions. CPU load.

[arto13]

Hello. Have a question about minimization CPU load.
I have composite definition X. X contains another composite definition Y = (5a +5)
What formula requires fewer CPU resources 1 or 2:
1. X = Y + Y*Y
2. X = (5a +5) + (5a +5) * (5a +5)

Y - composite Definition.
Y = (5a +5)

PS. Sometimes i have 5 steps like this in 1 formula. And my new machine loads too much.

In general I'd say having one composite call another will use more cpu. I think that's what you mean with this

Y - composite Definition.

1 would also be faster than 2
