1·Again, this is an extreme example, but it shows that the scheduling overhead of contention is not trivial.
这又是一个极端的示例，但它表明争用的调度开销并不是微不足道的。
2·We can use randomized index key columns to reduce contention, but at what cost?
我们可以使用随机化的索引键列来减少争用，但这有何代价呢？
3·The memory manager allocates memory to threads in chunks to minimize contention on the heap lock.
内存管理器以块的形式将内存分配给线程，以最小化堆锁定争用。
4·We found significant contention on the lock that protects each network device's transmit queue.
最后在保护每个网络设备的传送队列的锁上发现了严重的争用。
5·So you can do super-efficient caching and avoid locking and contention problems.
所以可以进行超高效率的缓存，避免锁定和争用问题。
