The youtube flash files can not play fluently in full screen mode on Crownbeach, but just show frames one after another. The problem is quite obvious on crownbeach. On samsung, the quality is much better.

Reproduce steps:
----------------
1. Launch midbrowser
2. Visit http://youtube.com
3. Choose a flash to play
4. Enter into full screen mode

Current result:
----------------
1. The flash can not be played fluently in full screen mode

Expected result:
----------------
The flash should be able to play fluently

Basic root-causing log:

Carl & Rob, could you pls. help to root cause the issue?

Just tried again, and found the problem may relate with the memory. In 1G memory system, the situation is much better, but in 512M memory system, the problem is obvious. Do we have any ideas to solve the problem?

It's easy enough to verify if memory really is being swapped out by
either doing a 'swapon -s' or even just turning off all swap before the
test (swapoff -a) and see if the browser is killed.

Beyond this, you need to profile the system to find where all the cpu
cycles are being spent.

Fan,

Please try this with the new FF3.0 based midbrowser. If the performance is acceptable, please close t his bug.

Thanks,
Carl

Verified that FF3.0 based midbrowser performs much better.
