Memory usage of Aspose Words for Java

Dear Aspose Support,

Just wonder how much memory will be consumed by merging 12 documents to create a new one. I know it is hard to tell but I just need some rough estimations.

The documents size will be 100k+.

Each of the documents has 400+ content controls and 200+ pages.

The merging operation can be triggered in different user sessions.

Thank you very much in advance for your help.



Hi Michael,

Thanks for your inquiry. It is quite difficult to answer such questions because CPU performance and memory usage all depend on complexity and size of the documents you are loading/generating. In terms of memory, Aspose.Words does not have any limitations. Usually, Aspose.Words needs 10 times more memory than the original document size to build a DOM in the memory.

Moreover, a document size on disk is usually smaller than document size in memory. There is no fixed relationship between disk size and memory size, it depends on the complexity of the document, formatting etc, but memory footprint will always be bigger than size on disk. If you have a document 1.7mb on disk and 12mb in memory it could be reasonable. It could be reasonable for some documents at some point in their life (remember garbage collector is always working etc).

Hope this answers your query. Please let us know if you have any more queries.
