My process in background hogs 96% CPU but when ran in foreground its almost zero.

Hi, I am new to this Forum.
I am trying to solve one problem: When i run my process in background it hogs around 96% of CPU.
But when ran in foreground, CPU utilization is almost zero.
Is there any difference b/n a background and a foreground process wrto CPU utilization?

Any help in this regard will be appreciated.

Thanks

I think the post is in the wrong thread..sorry..

The process has 4 threads, 2 of them are TCP server threads waiting for two different client to connect. 3rd one is waiting on shell for user input, it is in while(1){ fgets() }. 4th thread is waiting on a queue to receive some messages.
