Better to have 1 large union or multiple small unions? (Performance)

[koi1299]

I have a model containing 3 unions. I know unions are worse than parts for performance, but performance-wise, would it be better to Union them together into 1 large union, or to keep them separate as 3 smaller unions?

Thanks in advance.

1 large union should be better here. Can I see the object?

Avoid using unions, If you still prefer them, you can convert the union to mesh and reupload it mesh part.

It looks like that can easily be made with parts. Maybe go for them instead?

Thanks, yes I have made this with parts but I was just checking in this situation what would be better to use.
