如果使用并行处理，服务器可以按照任何顺序执行成批请求。
In case of parallel processing, the server can execute the batched requests in any order.
主服务器的日志写入和对于备用服务器的发送在主服务器上是并行执行的。
The log write at the primary and the send to the standby are performed in parallel on the primary server.
哪怕是最简单的一个对象，都有可能需要执行一些脚本——服务器也因此要对其进行大量的并行运算。
Even the simplest objects may have some scripting attached to them and a given server may be running hundreds of them simultaneously.
此外，一个Domino服务器通常只能并行地执行一定数量的代理，因此对于吞吐量而言，这可能成为一个限制性的因素。
In addition, a Domino server usually executes just a certain number of agents in parallel so that this might become a limiting factor with respect to throughput.
在API的角度看，在一个VM上并行执行事务和在远程服务器上执行事务没有本质的区别。
From the API side, there's no real difference between transactions executing concurrently within the same VM and transactions executed against a remote server.
要在单个VM上执行并行事务，只需要在数据库文件上打开一个服务器，指定其运行端口为0，这样声明就不会有网络的发生。
To use concurrent transactions within a single VM, we just open a db4o server on our database file, directing it to run on port 0, thereby declaring that no networking will take place.
