I/O bound (Input/Output Bound) is a term used to describe an application whose performance is limited by the speed of its input/output operations, such as reading from and writing to files or databases. In this case, the application will take longer to finish if more data needs to be read or written. I/O-bound applications are typically CPU-light but require large amounts of disk or network access in order to function properly. Examples of I/O-bound applications include web servers, file processing programs, and database queries. Generally speaking, improving I/O performance requires faster storage systems such as solid state drives (SSDs), increased memory, better networks, or faster processors. By making any one or more of these improvements, I/O-bound applications can become more responsive and have improved performance. The overall goal is to reduce the amount of time it takes for an application to complete its tasks.  

When troubleshooting I/O-bound applications, identifying and improving their bottlenecks should be a priority as they are often what limit the performance of the system. This can include optimizing any databases that are accessed or using tools such as caching and queues to speed up data access. Additionally, checking the load on any shared resources like networks can help find points of contention and allow for improvements in those areas as well. When dealing with I/O-bound applications, having an understanding of where most of their activity is coming from can be helpful in determining which parts need improvement. With careful analysis, improved performance can be achieved without needing to make drastic changes or investments in hardware.  

Overall, I/O-bound applications can be challenging to optimize due to the amount of external factors involved. The good news is that with careful planning and good practice, these applications can still run effectively without requiring expensive investments. Learning how to identify and address their bottlenecks is essential for improving their performance and ensuring they work reliably under any load. With the right approach and tools, I/O-bound applications can perform just as well as CPU-heavy programs.
