As far as I can see almost all memory is set write-back. The memory at the far end belongs to some hardware, see /proc/iomem below.
Are there any other suggestions why our machine is so slow, or perhaps 'write-back' is the reason??? If You need more info, please tell me, I will gladly provide it. Or if I can make any tests / benchmarks, ask for it.
Sincerely,
Robert S.
