Does anyone have any experience to which is a faster
solution , a 200mhz arm9 or a 400mhz xscale processor

So you're wondering if a 200MHz ARM processor is faster than a 400MHz ARM
processor?

Depends on which XScale, and what you are doing. In some cases a 200 Mhz
ARM920T will outperform an XScale device. It all depends on what you are
doing.

Well, it's more like wondering if P4 Mobile 3.06 will outperform Pentium-M
1.7. The answer is - you need to test to find out.

And what to test as Steve points out. Maybe the ARM9 has an FPU...

its pretty much just little bits of everything, my ce image is about 12meg
now using
a sharp a404 which is an arm 9 and its slow just navigating "my device"
viewing
local folders. it seems when you add in "Wired Local Area Network" to the
bsp that is
the killer. I did the pain staking exercise of building images one feature
at a time
and when you get to items like Compact Flash , soap server and wired lan
they
suck up all the resource from the arm9. So with that does anyone think the
xscale
what ever version PXA27xx or other think I could get any better results.

It's not processor that those things are sucking up, especially if you
aren't actually connected to the network. They're using up RAM. Compact
Flash support does *nothing* unless there's a card installed and you're
browsing it or whatever. The same is true of wired network support; no
network connection, no processor cycles used.
