远程并行执行并不适合小型任务，因为机器间通信的系统开销不容忽视。
Remote parallel execution was not favorable for smaller tasks because the overhead for communication between the machines was significant.
随着任务量的增加，机器间通信的开销与在单个机器上执行全部任务的开销相比逐渐变得微不足道。
As I increased the task size, the overhead associated with communication between machines diminished in comparison to the overhead of executing the entire task on a single machine.
其结果是，不管应用程序是运行在同一台机器上还是运行在网络上，在进行数据库操作时，它都无需进行进程间通信。
As a result, no inter-process communication, either over the network or between processes on the same machine, is required for database operations.
