My biggest complaint that I have when using Open Office is the speed of the application. It loads terribly slow for instance and it only topped by the time GIMP needs to start up on my PC.
Way to slow to edit a document quickly in my opinion unless you have the application open all the time anyway. There are however options to speed up Open Office which you can do by editing a couple of parameters in the Open Office settings.
I was a bit skeptical at first but soon found out that the changes would indeed speed up Open Office tremendously. Start Open Office and click on Tools > Options. This should open the configuration. Click on Memory in the left menu and change the following settings to the values you see on the right.
- Number of Steps: 30
- Use for Open Office: 128
- Memory per Object: 20
- Number of Objects: 20
Click on Java in the left menu afterwards and uncheck Use a Java Runtime Environment. Click OK and restart Open Office to see how fast it is now. That's really a difference don't you think?
Update: Recent versions of the popular Office suite show improved loading times. The tweaks outlined above are still valid on the other hand, especially the bit about removing the Java Runtime Environment from the Office suite to speed up the load time. That is, of course, only an option if you do not need Java for functionality in the Office software.
Another possible option is to move the Open Office installation to a faster drive. Moving it from a conventional hard drive to a Solid State Drive can improve the loading times of the Office software by a lot. I'd say that unchecking the Java option is your best bet to speed Open Office up though.
You can alternatively uninstall Java completely instead if you do not really need it, as it will have the same effect.
Another thing that you may want to try out is ti disable loading printer settings with the documents which may speed up the loading and performance especially for spreadsheet files. You find the option under Tools > Options > Load/Save.
