Subject: Re: IO latency - a special case

Hi Ted,

I have no idea what "sar" is, and a google search doesn't appear to
reveal anything useful.  Where can I get this "sar" tool?

I also do not have "iostat" on my system, and again, google does not
appear to reveal an official page for that, and gentoo doesn't appear
to have a package for it.

I have output without those tools, if you want that.  I hit a 1 minute
load average of 46 this time, and 46 uninterruptible processes.

Thanks.
