Primarily, XFS USES allocation groups so that it can efficiently handle parallel IO.

主要原因是，XFS使用分配组，以便能有效地处理并行io。

We design and implement parallel IO strategy to solve the insufficiency of the existing strategy.

针对已有的主端IO策略中存在的各种缺陷，设计并实现了并行IO策略。

Allocation groups also help to optimize parallel IO performance on multiprocessor systems, because more than one metadata update can be "in transit" at the same time.

分配组还有助于在多处理器系统上优化并行io性能，因为可以同时有多个元数据更新处于“在传输中”。

There are three main ways to accelerate the performance of AnyStorage storage virtualization gateway: cache acceleration, parallel IO and random write acceleration.

而AnyStorage存储虚拟化网关的性能加速手段主要有三种：缓存加速、并行IO技术与随机写加速。

Thanks to allocation groups, the XFS code will allow multiple threads and processes to continue to run in parallel, even if many of them are performing non-trivial IO on the same filesystem.

多亏了分配组，XFS代码将允许多个线程和进程持续以并行方式运行，即使它们中的许多线程和进程正在同一文件系统上执行大规模IO 操作。
