Thank you krackedpress, I checked the box - Chargement de LibreOffice au démarrage du système - (= Load LibreOffice when the system start). The first time I click on my file's link I have to wait 50 sec. The second time 32 sec. If I open LO I wait maximum 6 sec. Then I click on Calc and I wait less than 1 sec. Now I choose my file in the recent documents list and I wait around 30 sec. Now I look at my netbook and I remember how big was this machine in 1979. I remember how long we had to wait sometimes... The most important is : today we have Writer, Calc... for nothing. And it works fine compare to /others/ you have to pay a lot for. So it is ok. After somedays I will play /again/on my desktop. I am going to bring it to the shop where they will change the CPU (a second hand Core 2 duo E 8400 instead of P 4 531), put 8 Go Ram (4 Go x 2) and I will /run/ on W7 64 bits and Linux Mint 64 bits too. This will be the future for me... Thanks again, Jacques -- View this message in context: http://nabble.documentfoundation.org/How-I-can-reduce-the-loading-speed-of-Calc-tp4047785p4047826.html Sent from the Users mailing list archive at Nabble.com. -- For unsubscribe instructions e-mail to: users+help@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
