# Performance and Scalability

This section covers the key factors that ensure the campaign runs efficiently and maintains optimal system performance.

- **Concurrent Call Limits**  
    Defines the maximum number of calls that can be handled at the same time, preventing system overload and ensuring stability.
- **Load Balancing Across Dialers**  
    Distributes call traffic evenly across multiple dialers, optimizing resource usage and avoiding bottlenecks.
- **Queue Management**  
    Controls how calls and leads are organized in queues, ensuring proper handling order and minimizing wait times.
- **Resource Allocation (Channels, Trunks)**  
    Determines how system resources such as channels and trunks are assigned, ensuring sufficient capacity for call operations.
