Dear Dimon,
Thanks for your project.
The memory usage depends on not only the content of the document but also the system resource, e.g. running environment, available memory and so on. Usually, Spire.PDF needs more memory than the original document size to build a DOM in the memory. Your PDF has 1300+ page, when finding the text page by page, inevitably it needs some memory to do it. In addition, I noticed you used win10(RAM 4GB) and VS2017, I am afraid a small amount of available memory is left.
Anyway, we will check if there is any approach to reduce the memory usage, if there is any news in the future, we will let you know.
Sincerely,
Betsy
