Interrupt latency is the delay between when an external event occurs and when your computer starts responding to it. This delay can range from milliseconds to seconds depending on what kind of request was made and how busy your computer is at that moment. The main causes of interrupt latency are hardware limitations and resource contention.   Hardware Limitations   Your computer’s hardware determines how quickly it can respond to requests for data. If your computer has an old processor or not enough RAM, then its response time will be slower than normal due to the limited resources available. Additionally, if you have too many applications running at once, then they will compete for resources which can also slow down your system.   Resource Contention   Resource contention occurs when multiple applications are trying to use the same resources at the same time. For example, if two applications are both trying to access the hard drive at the same time, then they will have to wait their turn before they can start reading or writing data from it. This waiting period adds up over time, and increases interrupt latency on your system.   Reducing Interrupt Latency   To reduce interrupt latency on your system, there are a few steps you can take: upgrade hardware components like RAM or processors; close unnecessary applications; make sure all drivers are up-to-date; disable programs that run in the background; and limit multi-tasking where possible. Additionally, make sure you only install trusted software on your machine, as malicious software can also cause resource contention and lead to increased interrupt latency.
