Hi Fadia ,

                 Welcome to forum .

I will suggest you a heap and thread dump analyser ( from IBM site) for  the Java process ........it will clearly show if you have  java threads that may have been waiting , if at all any .In addition to this ,an  incorrectly configured JVM paramaters in application server , can adversely affect performance. It's best to cut and paste the usage o/p ( from top , glance) to application people....and have them look at it.
