Hi Steve, The only explanation I can think of is that the flood of messages overloaded your logging. I tried running
iozone 1 8192
and got a more modest set of log messages showing the transition from write to read. You should see an fsync, a close, then the file being opened, and the count of the number of pages cached. On the NT server, it shows 256 pages cached after finishing the write.
Regards, Bill
