Improving performance

Hi,

I am running SEONote on a usb key. I installed it and copied the folder to the drive (nothing new...) . However, it is slow to load, apply new settings and also slow at closing. I tried Keynote and had the same issues. Does anyone have any suggestion as to how to improve the speed (and therefore the usability) of Seonote. Is someone using it finding it also slow ?
thx,
