Not sure where you read such things about two component instances running in different processes. ServiceMix uses only one process and the JBI makes no mention of processes, I guess you misunderstood something here. Not sure also where you grab your performance figures.
Performances really depends on your use case: if you put two services in the bus on the same ServiceMix container, inter-component invocation will be amazingly fast (it's just about passing an object from one component to the other without any serialization or such). If one service invokes the other one by mean of HTTP or JMS or any other protocol, the performances will surely drop by a big amount of course. So unless your services are deployed on two different containers, they should use in-VM communication, so it will be fast enough.
