LO converts an XLSX file (via a filter) to data structures that the ODF parser understands and stores the data structures in memory. The larger the Excel file, the longer it takes to parse those structures and manipulate them in RAM. You may find that this solution doesn't scale well for you either on large files such as the ones you are envisaging. I don't use LO enough with large files in this way to say. Your best chance of getting a more comprehensive answer would be to ask your question on the libreoffice developer list, or look out for Markus Mohrhard, Eike Rathke or Kohei on the libreoffice developer IRC, they're the main LO Calc experts.
