Traces of the IOS are captured using blktrace and same is being replayed using blkreplay. I want to check the parameters like throughput , queue depth and IOS so we are using the tools like seekwatcher and iowatcher. There is a huge difference in the parameters of the replay. Even there is a difference in disk offset also. why is it so ?

sounds like you are not using a good reply tool with high-fidelity. Try btreplay to get more accurate results.
