Issue about Cortex-A9 Dhrystone performance

Hi,

We found the following document on Cortex-A9 performance.

List of ARM microarchitectures - Wikipedia, the free encyclopedia

Which claims 2.5 DMIPS/MHz per core for Cortex-A9 2GHz@2 core. However, our Dhrystone result on Cortex-A9 1.2GHz@2 core only showed roughly 1 DMIPS/MHz per core.

We downloaded the Dhrystone benchmark from the following link and cross-compiled it with gcc version 4.5.2.

We realize that Dhrystone measurements will vary due to differences in compilers and OS. And I would like to know whether our result is reasonable or not?

Best,

Ying
