If service B returns before Service A an error occurs. Service A is lightening fast, and Service B is a slug. Service A incurs an unexpected performance penalty for every new user added to the system.
This incremental slight performance degradation adds up, eventually additional system load such as a periodic Virus Scan on System A has a chance to push it over the edge.
