The SWAPPOLUBE Editor is a graphical user interface to the configuration of several parameters of the N900 kernel with the aim to make it faster.

It has been created with PyQT (PyQt v4.7.5 for Python v2.6) and the functionality is provided by Python.

The package changes a number of kernel parameters when installed and adds a script to event.d to make the changes persistent.

The issue has been discussed in two talk.maemo.org threads: "How to set swappiness" and "Swappolube to lubricate your gui".
