This actually looks like a sd bug... forwarding it to the storage
alias to see if anyone has seen this...

I wonder if some of this could look into a dynamic policy. For

Since you were already using filebench, you could use the
'singlestreamwrite.f' and 'singlestreamread.f' workloads (with
nthreads set to 20, iosize set to 128k) to achieve the same things.
With the latest version of filebench, you can then use the '-c'
option to compare your results in a nic
