Re: What's the bottleneck here (CPU usage)

- the display is my HD TV and Ubuntu is driving it at 1920x1080 through the VGA port (I'm using a VGA > HDMI adaptor)
It's choking on streaming videos, such as YouTube and national news shows.
Even with the video in small-screen mode, htop reports the CPU running at 100%. In full screen mode, forget it -- too stuttery to watch.
I tried FireFox and Chrome and get the same results.
With the video paused I see 15% cpu usage. Memory usage is 450MB out of the available 1GB, so I don't think it's disk swapping causing the problem.
Do I need a faster motherboard to watch full-screen videos?
No, you need a faster processor to run full-screen videos.
You cpu is the bottleneck. Flash is cpu hungry if you do not have a proper video card to offload the work. Since your integrated card is not worth mentioning, your cpu have to do all the work
