Sometimes you may feel Libreoffice is taking longer than expected to start.
No doubt Libreoffice is a bit heavy application, it might take some time to start first time, but it should not be enough to annoy users.
In reality LibreOffice is taking 2-3 seconds to start even after being just closed, and the splash is annoying too.
This LibreOffice slow startup problem was enough to keep me away from it for a long, another reason was it's a GTK+ application, which I don't like much.
So here some simple tweaks to improve libreoffice performance and make it start faster, lets get started ....
1. Increase memory limit and enable systray Quickstarter
LibreOffice doesn't take advantage of additional system memory with the default settings. Open up the Options under the LibreOffice Tools menu, and navigate to the Memory option.
Increase all Graphics Cache related options and check the Enable systray Quickstarter option. Example screenshot below.
The Qucikstarter option will speed LibreOffice startup significantly, almost instantaneous opening without the splash.
2. Enable OpenGL for graphics rendering
Enabling OpenGL will result in faster rendering of graphics heavy contents, like presentations in LibreOffice Impress.
Open up the LibreOffice Options like before and now navigate to View option.
Check the Use OpenGL for all rendering option and Force OpenGL even if blacklisted option and restart LibreOffice, that's all.
Here more settings related to the view option, https://help.libreoffice.org/Common/View_2 .
So, I hope now LibreOffice is starting fast and handling graphics heavy documents more easily. Don't forget to share your thoughts and suggestions in the comment section.
