Mesh topology is known for its ability to provide better performance due to its unique structure, where each device is connected to multiple other devices. This extensive interconnectivity allows for multiple pathways for data transmission, which can significantly enhance the network's reliability and speed. If one connection fails, the data can be rerouted through alternative paths, reducing the chances of network downtime.

However, the increased performance comes at a cost. Setting up a mesh network typically involves higher installation costs compared to other topologies. This is because it requires more cables and hardware to connect each device to every other device directly. The complexity of this setup also necessitates advanced configuration and maintenance efforts, adding to the overall expense.

In contrast, other types of topologies, such as bus and star, generally offer easier and less expensive installation but may not provide the same level of performance and fault tolerance as mesh. Therefore, while mesh topology requires a significant investment, its superior performance makes it a preferred choice for networks where reliability and speed are critical.
