Migratory lines feature allows for the efficient movement of modified (dirty) data between CPUs' caches without the need to write the data back to a lower level of the memory hierarchy (like L2 cache) and then read it back into another CPU's cache. This feature is particularly useful in multi-processor systems to reduce memory access latency and increase overall system performance.
