Data Debit when it's a multirole device

Question

Hello, I am working on a project based on a central/peripheral NUS application, with nRF51822 and SDK 12.3 . 
 
 I Want to know if the debit of data exchanging is lower when it's a multirole device ? 
 
 Thank you for your help.

What do you mean with debit of data exchanging? Do you mean data throughput? 
 If this is the case, the answer will most likely be yes, since you cannot have every link optimized for maximum throughput. For example, you cannot have 20 links with connection intervals of 7.5 ms. You will have to compromise somewhere. I do not know exactly the numbers, but I think it is safe to assume that the maximum data throughput achievable will be lower as you add more links to your application. 
 However, if you have relaxed requirements, let's say one link with a connection interval of 200 ms and you plan to add three more links with the same characteristics, I don't think you'd have a problem. But this is something that you need to test.
