--- Comment #5 from Jeff Fortin Tam <nekoh...@gmail.com> ---
Actually not just the Lenovo accessories spreadsheet, but also the sample
spreadsheet at
https://fortintam.com/public/libreoffice-augustin-benchmark--million-rows-spreadsheet.ods
exhibits the problem in a similar way. While this spreadsheet was originally
used as part of bug #151207 to show one various areas where multithreading
would be beneficial, it can also be used just as a general file opening
performance benchmark, even if file opening was multithreaded.
Indeed, presumably, even if it would be multithreaded and would use all 4
logical CPUs to open the Lenovo spreadsheet instead of 1, it would still take
50 seconds (instead of 3 mins 20) on that computer, which is still much slower
than the 3 to 13 seconds that Gnumeric and Excel can manage. So, I can imagine
that multithreading could help, but wouldn't be the entire solution by itself.
