Hi folks,
I was trying to get answer to my question around, but no one knows.
I do have DMA turned on, etc, yet - on extensive harddrive operations wait
time is 90+% , which means that machine is waiting, rather than doing
something meanwhile. (I guess).
Can someone describe to me , in more detail why is that happening, and what
steps should I consider to avoid it ? I couldn't find any answers that would
have help me on net.
thanks.
From later posts I suspect that your disk performance just sucks, but
do use one of the monitoring tools and follow the actual disk work, in
term of seeks and transfer rate.
I've been looking at high iowait while disk and network are (nearly)
idle, but it sounds as if you just have a bad match of CPU and disk speed.
Can you borrow a USB drive to use for some testing? USB 2 needed to be
faster than your old 4200 rpm drive.
