The lower speced machine is far,far,far quicker (gnome etc).
Anyone any ideas how this could be?
If you are building your own kernels, make sure that you don't
accidentally turn on CONFIG_DEBUG_PAGEALLOC in your .config.
You can check this by doing a 'grep CONFIG_DEBUG_PAGEALLOC
/usr/src/linux/.config'.
It should not be set.
I speak from recent experience with this matter; I enabled debug in my config so that I
could use the sysrq key. Unknowingly, I turned on pagealloc debug also (the default if
debug is enabled) - and it took me a little while and some effort to track the problem
down. I checked the stock FC4 kernel, and it of course does not have this config set.
But be wary if building your own kernel.
