Abstract
As very large digital library collections become more commonplace, software tools must adapt appropriately. This paper reports on an evolution of the Greenstone Digital Library software to support parallel processing during the collection building phase. A series of experiments were conducted to first establish a basic speed-up factor, and then deconstruct the parallelisation process to understand the execution profile of the application. Several bottlenecks were identified and resolved to further improve the performance. The adaptation of Greenstone confirms that the build phase is indeed a suitable candidate for parallelisation; and suggests that parallelisation of processing is a new avenue for exploration in emerging digital library architectures.
