Thus, for a typical program invocation with N options, the code needs only O(N) [N*O(1)] comparisons—an order of magnitude improvement over the legacy code.
因此，对于具有N 个选项的典型程序调用，代码只需执行O(N) [N*O(1)]比较 —这是对遗留代码的巨大改进。
For example, if the complexity order of the current technique is O(n**2), speeding up the steps by 10x is a lot less helpful than finding an O(n) substitute.
例如，如果当前技术的复杂性等级是O(n**2)，那么将这些步骤加速10倍远不及寻找 O(n) 替代品来得有用。
In order to improve I/O performance and reduce I/O implementation time, a kind of command combination strategy is used.
在磁盘阵列中，为了提高I/O性能，减少I/O执行时间，采取了将分解到同一磁盘上同命令类型且操作数据地址相邻的多I/O命令合并的策略。
