High-Performance Loader User's GuideThe describes how to use the HCL Informix® to load and unload large quantities of data efficiently to or from Informix® databases.
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.
Increase the commit interval

Increase the commit interval

In the deluxe modes, the commit interval specifies the number of records that should be loaded before the transaction is committed (see The Load Options window). Low values (frequent commits) degrade performance and high values improve performance. If you increase the commit interval, you might need to increase the size of your logical-log buffers.

While larger commit intervals can speed up loads, larger commit intervals require larger logical-log space and increase the checkpoint time. These side effects impact other system users during onpload operations.
