这些因素使多玩家在线游戏引擎可以利用并行数据库技术，比如对称多处理器，以及其他大内存系统。

These factors allow a multiplayer online game engine to take advantage of the power of parallel database technology, such as symmetric multiprocessors, and other large memory systems.

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”。

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.

由 -XX:+UseParallelGC 启用的并行清除收集器是年轻代收集器，针对多处理器系统上非常大(吉字节以及更大的)堆进行了优化。

The parallel scavenging collector, enabled by -XX:+UseParallelGC, is a young-generation collector optimized for very large (gigabyte and larger) heaps on multiprocessor systems.
