I believe the use of only one core is 'normal', Open/LibreOffice appears to be a single process/thread. I use an 8-core i7 workstation [openSUSE 12.3/GNOME3.8] and opening my primary ODM [OpenOffice Master Document] pegs one core briefly at 100% while the other cores take the stray maintenance tasks [like zeitgeist,etc.. that get pinged whenever something, like opening a LibreOffice file, happns]. While the application is unresponsive for a moment it opens rather quickly [given its complexity]. The spreadsheet in question matters [if it is very complicated, contains nested formulas, has large images], as does your settings. Getting more cores probably is not the most effective way to more responsive performance. It is more likely a memory or I/O issue. If you have a class-10 SD card, if you copy the file to there, and open it [after rebooting], is it faster to open? If so then it is an I/O issue. If you open LibreOffice [not the file, just Libreoffice] and then exit LibreOffice, and then open the file is it faster? If so then it is the load time for LibreOffice and all its dependencies [many of which will now be cached] and you should enable a preloaded or LibreOffice quickstart to have that done ahead of time. How long does openning LibreOffice and creating a new document take compared to opening your ODS? When opening your ODS does it spend a lot of time at a particular phase - "adapting row height" for example? -- To unsubscribe e-mail to: users+unsubscr...@global.libreoffice.org Problems? http://www.libreoffice.org/get-help/mailing-lists/how-to-unsubscribe/ Posting guidelines + more: http://wiki.documentfoundation.org/Netiquette List archive: http://listarchives.libreoffice.org/global/users/ All messages sent to this list will be publicly archived and cannot be deleted
