Just a heads up this also works very well for me. Especially with unpacking of large zipped files etc I tried using the webos game manager this morning my m900 struggled unpacking the ipk files for settlers and eventually it crashed out with a full reboot also the ui was very unresponsive during that period.
I used the settings described here and it worked a treat and a hell of alot faster and no real impact in terms of responsiveness .
Glad I remembered about this post :¬)
Cheers
