Package: libreoffice Version: 1:4.3.3-2 Severity: important With /home on network file system (NFS or similar) libreoffice is lagging miserably on basic operations like when libreoffice just started or new writer document is opened etc., as well as on innocent moves between tabs under [Tools -> Options -> Libreoffice] even when nothing is changed.
Strace-ing revealed the problem which is aggressive re-write of "registrymodifications.xcu" in "~/.config/libreoffice/4/user": on almost every action in libreoffice a new temporary file is created (in user profile folder) and renamed to "registrymodifications.xcu". The latter is about 1 MiB and about that much data is written very very often. But the worst thing about it is that configuration is not written in background -- instead it is a blocking operation causing very uncomfortable lag in user interface. Also it seems that often configuration file is unnecessary (re-)written when nothing has changed. What can be done to minimise rewrites of "registrymodifications.xcu" or reduce frequency of configuration save? An ugly workaround may be to disable configuration changes completely by setting profile folder read-only (e.g. `chmod -c u-w ~/.config/libreoffice/4/user`) but I hope that better solution may be available. Thanks.
