Hi, @shiva.k

I have investigated the issue using next Java parameters: -Xms512m -Xmx6g and the licensed GroupDocs.Viewer for Java v21.2.
For testing, an empty Maven project with the exec-maven-plugin was used. The project was run using the command mvn clean compile exec:java. The Java version used is 1.8.0_361.
For all pages processing took 08:06 min, while for 5 pages it took 03:04 min.
Here is a project (16.0 KB) so you can check the results yourself. It’s possible that the issue may lie in the project where GroupDocs.Viewer is being used or in its interaction with other libraries.
Running the sample with less than 6Gb memory in some cases leads to an out-of-memory error. Despite processing only 5 pages, GroupDocs.Viewer still needs to load and analyze the whole file. We are working on improving performance, but it is not the primary goal at the moment.
Feel free to contact us in case you have any problems or questions.

Best regards,
Oleksii
