Manage the High-Performance Loader
HPL performanceYou can improve the HPL performance by preparing an environment that is optimized for the particular load or unload job that you are performing.
HPL performance hintsIn general, the performance of the depends on the underlying hardware resources: CPU, memory, disks, tapes, controllers, and so on. Any of these resources could be a bottleneck, depending on the speed of the resource, the load on the resource, and the particular nature of the load or unload.
Choose an efficient formatWhen you load data to or unload data from a source that is not HCL Informix®, you can use fixed or delimited format in an appropriate code set such as ASCII or EBCDIC.

Choose an efficient format

When you load data to or unload data from a source that is not HCL Informix®, you can use fixed or delimited format in an appropriate code set such as ASCII or EBCDIC.

In general, ASCII loads and unloads are the fastest. If you are using onpload for a machine or schema reorganization, choose the no-conversion format. Delimited and fixed ASCII formats are comparable in behavior except when VARCHAR data is present. If the schema contains VARCHAR data and the length of the VARCHAR data varies greatly, you might want to choose delimited format.
