What is the performance impact of CPU affinity?
CPU affinity refers to the assignment of a process to a specific CPU core. This can improve performance by reducing cache misses and context switching.
How does it affect multi-threaded applications?
In multi-threaded applications, setting CPU affinity can help ensure that threads run on the same core, which can enhance cache utilization and reduce latency.
Are there any downsides to using CPU affinity?
Yes, while CPU affinity can improve performance, it may also lead to underutilization of CPU resources if not managed properly, especially in a multi-core system.
Can you give an example of when to use CPU affinity?
Sure! For real-time applications, like video processing, setting CPU affinity can help maintain consistent performance by minimizing interruptions from other processes.
