Thanks for quick reply ,

                  Actually we making Bio-Metric devices using Android 
Platform. There I've been using a algorithm for matching the templates. 
Here i have facing big challenge. 

                  In case of Linux (RedHat, Ubuntu) this algorithm gives 
milliseconds to compare 100 templates.
And also in Windows 3 seconds. But in Android it leads 30 seconds. It's 
huge different right. 

                 My biggest doubt is Why this huge different even though 
using same Linux kernel. 

*My Platform Specification:*
*
*
*          *1. ARM cortex A8 processor with 750 GHZ.

          2. Beagle Bone  is the developing kit. 
    
          3. That algorithm has fulfill ISO standards.
