@asidana: it only updates 3 feeds at a time, so the total number of feeds you have shouldn't dictate the amount of CPU used when updating. But it does take between 60 and 90% cpu.

@tpaixao: when you close the app, it saves its current state to disk. That seems to be taking quite a bit of CPU and time if you have a fair amount of feeds.

@ofels: external browser does mean MicroB. I don't think there is a default browser setting in Maemo that I can use (like you can find on a desktop OS).
