The load utility takes advantage of a hardware configuration in which multiple processors or multiple storage devices are used, such as in a symmetric multiprocessor (SMP) environment. There are several ways in which parallel processing of large amounts of data can take place using the load utility. One way is through the use of multiple storage devices, which allows for I/O parallelism during the load operation (see Figure 3). Another way involves the use of multiple processors in an SMP environment, which allows for intra-partition parallelism (see Figure 4). Both can be used together to provide even faster loading of data. For more information, see Optimizing Load Performance.
