Swapping willl always kill performance, as the CPU is busy pushing pages out to the eMMC which is rather slow.
The memory usage for browserd and Xorg seem reasonable though (about 20% each)

I just got the "pc delivering insufficient power to charge battery" for the first time since December - I think because of the constant CPU usage.
I suggest using htop and sorting by MEM usage. See what's eating memory. Also, those BBC pages had the iPlayer on them, which loads Flash, which has always been a huge source of performance issues for me.
As I say, a bit of zoom & everything is fine. I don't think that's consistent with Flash problems...

I haven't noticed it slower, but I have noticed a couple of "quirky" things. What they mean I don't know, for example:
It seems much easier to swirly zoom now.
After zooming, images and text doesnt seem to adjust as quickly as they used to (resolution wise)
Sometimes when scrolling a black line appears and flashes across the middle of the webpage pane and disappears once you stop dragging with your finger. I hadnt noticed that before.

Has anyone else noticed that browsing performance has dropped off a cliff with PR1.2? For some web pages at least.
Go to http://news.bbc.co.uk/ and click on one of the links at the top right, under the heading "other top stories".
As & after the page is loading, scroll around a bit.
My cpu is pegged. It feels like the whole system is swapping madly (it isn't, but it feels like it). Task switching is unresponsive or crawls. Xorg is taking 70-75% CPU, browserd is taking 20% or so. Disabling Javascript doesn't help.
This is a fresh flash of both FIASCO and eMMC for PR1.2.
I wonder if this is related to antialiasing or kerning as everything chills out a bit if I zoom in slightly.
Whats very interesting however is that the load isnt coming from browserd but rather Xorg.

If I go set Options -> Adjust View -> Show Images = None
then performance is great. Something to do with Xorg and bitmaps? There aren't *that* many images on the BBC pages.

I'm having a serious issue scrolling web pages with the arrow keys. If I press and hold the down button for anything longer than 1.5 seconds (more than just one "click") it scrolls uncontrollably down the page.
Especially when the page is loading, or if I (have a seperate page loading in the background).
It used to do this when the cpu was under full load (i.e. on phone startup), but now it seems to do it 70% of the time.
Anyone else experiencing this? Can you open a few pages and scroll through a loaded one normally, or does it scrol further down the page than expected?
Again, this is only using the arrow keys, thumb/stylus movement seems smoother... Using the arrow keys to moe around is my main use case, and this is making it almost useless... not happy

The tests I do with bit.ly/brmark were boosted 17%, which was quite good. Multitasking really lags and becomes unresponsive using the browser now. It did not do that before.
