I didn't find anything helpful with a quick Google search for "flash 10
multitheaded" but maybe it is an issue with multi-core machines?

That's a thought.  I have never been able to watch CNN videos on this dual-core
machine, even with Flash 10, but they work on the single-core machine that's
sitting beside it.  Both running F8.



have you considered/ever tried forcing flash &| the browser &| X processes to operate only on one processor (core) with taskset, just to see if it may be a context switching/processor cache bashing problem?


I have noticed on the dual Xeon 1.50GHz W/512MB I use, that if I lock X to the second processor, when visiting animated sites like
http://www.intellicast.com/National/Radar/Current.aspx?animate=true
The whole system is smother and the animation is less glitchy.
[with out locking X pulls ~85%cpu (of combined cpus),
with locking X pulls ~10-50%cpu (of combined cpus), on that page after it self reloads.]
