MIPS rate isn't a particularly helpful measurement, especially if you're just looking at peak MIPS. This is particularly important when comparing two completely different instruction sets, but even on identical instruction sets this is a misleading measurement. The core architecture, cache sizes, and memory bus will have as much or more impact on real-world performance.

Thanks for quick reply,

          I'm not using same hardware platform for all. Android alone running ARM core with 750 MHz , others are Intel core with 2 GHz. Compare with MIPS rate both core equally same. 

          Kindly tell me, If my platforms may differ which Android OS suitable for further development.

Yes, the Android linux kernel has been modified.

Android uses the "bionic" c lib.

Your test results look like you are comparing apples and oranges. E.g. do you use the same hardware for the test? If so, you need to use Android-x86 or something similar which may not be optimized (drivers etc.) for your platform...

I know Android uses the Linux kernel. I hope the Android developers did some modification with original Linux Kernel, especially in standard C libraries. My question is whether the processing speed of Linux and Android kernel are the same or different. I did some tests in different OS like windows and Redhat Linux and unbuntu and android. By the results Android is very slow. Android uses same Linux kernel... why this process variations but i know we cant expect same speed as in Linux, but I had huge differences (for example: Windows take 11 sec, Linux takes 4 sec, but Android takes 55 sec to complete my test) So What is the reason for this speed variation between these two linux kernels (Android and redhat both are 2.6)?

I'm using Android Kernel version  3.2.0.

Thanks and Regards,
