 Thanks for fast responding. I will try to use the threads and see how the
 performance would be.. actually I am using that for my artificial neural
 network and the problem is regarding to the ANN limitation when I used a 
big
 no of inputs. so one way to overcome this problem is by distributing and 
now
 I have like 3 networks in my system with slow processing. May be parallel
could have little effort.
