Hi Neto, I am ok. Here are the details. IOMeter (version - 2006.07.27): QDepth = 256 Worker = 1 Block Size = 512B and 4KB Runtime = 1 minute Access = SeqRd, RanRd, SeqWr, and RanWr OS Platform = Windows 2008 R2 Enterprise Server 64-bit FIO (version - 2.0.14): IODepth = 256 Thread = 1 Block Size = 512B and 4KB Runtime = 1 minute Access = SeqRd, RanRd, SeqWr, and RanWr OS Platform = Windows 2008 R2 Enterprise Server 64-bit But I am currently running a test to validate the previous results.

I use the same depth, access specification and the mixture between read and write. What I see is the difference between using thread in fio and worker in iometer? Can anyone point me the difference between thread and worker?
