Please find the source code below. It generates just a single page taking 40 seconds for the save method to execute. The culprit seems to be TextState API implementation . And this is the reason why I think the Aspose 4.5 API for java is not production ready (This version and com.aspose.pdf package was specifically recommended to be used by you in another forum thread ). We cannot have API’s like that which is open to use without specific documentation . If each row we need to set a different cell text state ,this is going take forever if the pages that is going to be generated is more than 50.
