Difference between 2.6.9 and 2.6.18 kernel configuration or tuning parameters


I found an interesting result with the throughput of a 15 GB file on 2.6.9 and 2.6.18.3. Both on the same Dell server.
The command used is "dd if=/dev/zero of=/mnt/NonYYLocalIO/15GBfile bs=4096 count=3932160" in both cases.
As dd command gives the throughput in MBPS after the command is completed. The observation is on 2.6.9 it is 56 MBPS and on 2.6.18.3 it is 37 MBPS.
What could be wrong with 2.6.18.3?

I doubt on the Kernel configuration and Tuning parameters.

Any idea?

Thanks,
Venkat
