What is one of the reasons for performance bottlenecks in applications?

Excessive load situations can significantly contribute to performance bottlenecks in applications. When an application experiences a higher volume of requests or transactions than it is designed to handle, the system may become overwhelmed. This overload can lead to slower response times, increased latency, and even system crashes if the infrastructure cannot efficiently allocate resources to manage the demand.

In situations of excessive load, the application's processing capabilities and resource utilization become strained. This can manifest in various ways, such as increased queue lengths, slower database queries, or resource contention among simultaneous processes, which ultimately impacts the user experience and the overall efficiency of the application.

While factors such as aesthetics, code complexity, and lack of monitoring tools can also influence performance, they do not directly result in immediate performance issues like increased load can. For instance, while overly complex code might make it harder to maintain and optimize an application, the direct impact of not being able to handle excessive loads is often more pronounced and urgent, highlighting the critical nature of managing scalability and resource allocation under stress.
