I have a sample containing 4000+ slide PPTX and it took around 5mins to complete processing. In some case it take much much longer and to some extend that it doesn’t seem to finish the processing. After much testing, the bottleneck was loading the file to powerpoint obj and output it. Im using Aspose Slide java V20.6. It seem like its relatively slower running in linux.
Here’s my sample and my sample program:
