[Buildroot] Raspberry Pi: recommendations for web kiosk

[Thomas De Schampheleire]

Hi,

We currently use a Raspberry Pi as a simple web-wall. It cycles every
two minutes between two (non-local) web pages, one of which contains a
few iframes.

While this can hardly be called a resource-intensive task, the
Raspberry Pi by no means performs this fluently. The pages load
relatively slow, and administration tasks on this pi also suffer from
hickups.

The pi currently contains a raspbian image (not done by me, I swear!
:-) ) and uses chromium in kiosk mode to display the web pages.

My basic question is: can I expect to get better performance by
setting up a custom buildroot image, or is rpi so poor in performance,
even for this mundane task?
Which packages should I select to achieve this?

Do I need an X.org or not really?
If X.org is needed, does 'Kdrive / tinyX' work on rpi, or should I
select modular x.org, and how do these compare.
(as you notice, I have never set up embedded boards with graphical stuff).

Which browser should/could I use? Preferably something that can run in
fullscreen mode as this is a kiosk-like board.

Is rpi-userland needed / recommended? How would I benefit from it?

Any other recommendations/tips are welcome too, of course.

Thanks,
Thomas
