Are there any consequences to having a lot of concurrent subscribe calls?

Trying to figure out the best way to structure publications and am interested in knowing the performance implications of having a large number of subscribe calls on one page. I’m assuming it’s probably better to reduce the number as much as possible, but I don’t know how DDP works so any insight is helpful.

I think the number of subscribe calls is of no significance compared to how much (total) data you load, and how often.
