Your workload has a number of concurrent threads that run batch. Some number of them can block on I/O at the same time, so you will see the b column. This will turn up in iostat in the queue length counter column "actv". So I would expect some correlation between actv and b.
Its not a problem as such, unless you want your batch jobs to complete sooner. Adrian On 5/18/07, Dale Ghent <[EMAIL PROTECTED]> wrote:

Be careful with %w... it's not that accurate. If you upgrade your e20k to Solaris 10, you'll lose that as iowait is no longer calculated (although the %w column is still there for output compatibility reasons. %b (% busy) is what you should be looking at instead. /dale _______________________________________________ perf-discuss mailing list perf-discuss@opensolaris.org
