The Multi-threaded Usage of PPT to Flash SDK

iSpring PPT to Flash SDK uses PowerPoint automation to retrieve the necessary information from the presentation. Microsoft PowerPoint was designed for single-threaded automation only and, thus, may fail to work when multiple presentation conversions are running simultaneously.

PowerPoint 2003 shows better stability during multi-threaded presentation conversion in comparison with PowerPoint 2007/2010. However, it is recommended to queue the uploaded presentations and convert them with the iSpring PPT to Flash SDK one by one.

To increase the presentation conversion performance on multi-processor systems, it is recommended to run several virtual machines (having PowerPoint and iSpring Platform installed) on one PC and distribute presentations among them. In this scenario each installation of the iSpring PPT to Flash SDK requires additional license.
