Does B1if leverage DI-API at all?

Hello,

I have implemented multiple DI-API solutions for one of my clients, but am not thrilled with the performance of DI-API in version 9.x.

I'm starting to investigate alternate integration options and am wondering if the B1 integration framework would be a better choice? I know that the B1WS interface still hits the DI-API behind the scenes (where the web service layer is really a wrapper around the DI-API framework). What about the B1if? Does this utilize the DI-API technology at all, or is it based on a different core layer? Would the performance be better and would the B1if be an optimal way to go in the future?

Thanks in advance for responses!
