What is cache partitioning and why is it important?

Cache partitioning is a technique used to divide cache memory into distinct segments for different processes. This helps in reducing cache contention and improving performance.

How does cache partitioning improve performance?

By allocating specific cache areas to different processes, cache partitioning minimizes the chances of cache thrashing, allowing each process to access its own cache more efficiently.

Are there any downsides to cache partitioning?

Yes, one downside is that it can lead to underutilization of cache if the allocated partitions are not fully used, potentially wasting resources.

Can you give an example of where cache partitioning is used?

Cache partitioning is commonly used in multi-core processors where each core has its own cache, ensuring that they operate independently without interference.
