Being a long time Mac user, and a heavy Impress user, I can tell that every pre-release of OOo and LibreOffice - since 2006 - has been slower than the final release, which seems to be the case for LibreOffice 5.0 as well. In this case, though, we have the additional burden of the operating system, as OS X 10.10 (Yosemite) has a number of problems per se, and there is a large number of applications behaving improperly or slowing down significantly either at launch or at shut down (for instance, Thunderbird takes ages to close). I will make tests on the less powerful Mac (the one I am using now is the top of the MacBook line, with 16GB of RAM, an eight core processor and a fast SSD, and tends to be always faster than anything else). The other MacBook is a more standard PC, with 4GB of RAM and a dual core processor, and is representing a larger number of user cases. I have hundreds of presentations on my hard disk, so I will make tests with different cases: native ODP, imported PPT saved as ODP, imported PPTX saved as ODP, etcetera. -- Italo Vignoli - Marketing & PR mobile +39.348.5653829 - email / jabber [email protected] hangout / jabber [email protected] - skype italovignoli GPG Key ID - 0xAAB8D5C0 DB75 1534 3FD0 EA5F 56B5 FDA6 DE82 934C AAB8 D5C0 _______________________________________________ List Name: Libreoffice-qa mailing list Mail address: [email protected] Change settings: http://lists.freedesktop.org/mailman/listinfo/libreoffice-qa Problems? http://www.libreoffice.org/get-help/mailing-lists/how-to-unsubscribe/ Posting guidelines + more: http://wiki.documentfoundation.org/Netiquette List archive: http://lists.freedesktop.org/archives/libreoffice-qa/
