Editing Release consistency (section)

=== Performance improvement over release consistency ===
Lazy release consistency can outperform release consistency in certain cases. If there is a system with little bandwidth between processors or it suffers badly from the higher overheads because of frequent propagation of small block of data versus infrequent large data block propagation, LRC can really help the performance.

Consider a system employs a software level shared memory abstraction rather than an actual hardware implementation. In this system, write propagation is executed at a page granularity, which makes it extremely expensive to propagate a whole page when only one block in this page is modified. Therefore, write propagation is delayed until a release synchronization point is reached and the entire page will be modified at this time and the whole page will be propagated.
