khtml rendering performance

[Luciano Montanaro]

I am testing konqueror (well, konqueror embedded, but khtml is the same)
on a slowish set-top-box machine, and I am facing a problem that on faster 
hardware is not so evident:

KHTML renders the the full page again each time some elements of it are 
dynamically changed. This makes the machine crawl when, for example, a 
clock as the attached one is running in the background.

Firefox is much better in this regard, and it manages to repaint only what 
has actually changed on the screen. 

Fixing this properly could vastly improve performance on highly dynamic 
sites, and I may try to help, but I suspect it is not an easy problem to 
address, and the fix would probably be quite invasive.

So, in the meantime, I'll have to work around this problem somehow.
Do you have any suggestions on how?
I can turn dynamically updated sections on my page in separate objects with 
fixed sizes, but the change would be quite invasive, and the result would 
not be particularly pretty to maintain.
