Reduce LibreOffice memory usage

libreoffice_compIf LibreOffice is taking longer to load on your box (mine is Ubuntu 12.04), a few settings changes can make it snappier. Open LibreOffice Writer and go to Tools ▸ Options ▸ LibreOffice and try the following changes (I am using version 3.5.3.2):

  1. General settings: Turn off Tips and Help Agent if you don’t need them.
  2. Memory settings: Set Number of steps to 15, Use for LibreOffice to 20 MB, Memory per object to 4 MB, Remove from memory after 00:08 minutes, Number of objects to 4. To always keep LibreOffice loaded in memory enable the QuickStarter. I omitted the last step as I don’t use office suites heavily.
  3. View settings: I just changed Icon size to small and turned off both Anti-aliasing options.
  4. Accessibility settings: Turn off Automatically detect high contrast mode… if it’s OK for you.
  5. Java settings: Disable Use Java runtime environment. Works for the version I have. Power users of LibreOffice, please read the comments below before proceeding with this step.
To disable the LibreOffice splash screen completely:

First method:

Edit the file /etc/libreoffice/sofficerc (In stock LibreOffice 4.2 /opt/libreoffice4.2/program/soffice) and change
Logo=1
to
Logo=0

Second method (the first method is better than this):

  1. Open /usr/lib/libreoffice/program/soffice. In stock LibreOffice 4.2 /opt/libreoffice4.2/program/soffice
  2. Find the following line (might be the last line in the file as well):
    exec $VALGRINDCHECK $STRACECHECK "$sd_prog/oosplash" "$@"
    and change to
    exec $VALGRINDCHECK $STRACECHECK "$sd_prog/oosplash" "--nologo" "$@"

Additionally I have removed some unnecessary (at least for me) buttons from Writer manually.
