Hi,

I have a PC(Windows 7, 32 bit) where JRE 6 is installed and when i execute the jar the javaw.exe CPU consumption is less than 1%. But when i execute the same in windows 2008 R2 64-bit machine with JRE 7 the CPU consumption is high goes around 21%.

Can any one point out why this behavior difference occurs or do i see something wrongly?

It's really hard to tell without knowing more details.

You could try using jvisualvm (a tool included with the JDK) to see what your Java program is doing.
