Slow performance due to high rate of software interrupts in application

Hello all,
I have an a client/server based multi-threaded application. The server's CPU consumption goes up-and-down from 0.1% to 15% although everything remains same. In 'top' output, I see that all things remain same except "%si" which is in complete sync with CPU utilization.

Is there a way to get to know which software interrupts are making up this percentage of "si".

I found "/proc/softirq" but I could not found a rpm for that.
