C++ UNO components that are instantiated in-process currently do not go
through a bridge when interacting with the LO API (although there have
been varying opinions about changing that, since it makes maintaining
backward compatibility more difficult): for such components, calling a
LO API method (or being called from LO itself) is just a C++ virtual
function call.

the best documented way to get this performance benefit is to implement
your client code as an extension.

there may also be a way to get there with less efforts, there are some
variables to add additional service rdbs to the soffice process
(URE_MORE_SERVICES/URE_MORE_TYPES) but i don't have any experience with
them; probably there is some way to implement what you want to do as a
service and then start it from inside soffice, if all else fails via a
trivial BASIC macro :)
