Optimistic lock coupling
WebThis crate provides a general optimistic lock. Description In actual projects, there are some lock-free data structures, especially database-related ones such as BwTree, Split-Ordered List(also known as Lock Free HashTable) when there are many write conflicts. WebWe perform 100M operations and normalize the CPU counters by that number. - "Optimistic Lock Coupling: A Scalable and Efficient General-Purpose Synchronization Method" Table 4: Performance and CPU counters for lookup and insert operations in a B-tree with 100M keys. We perform 100M operations and normalize the CPU counters by that number.
