I am trying to see the effects the changes in packet sizes on interrupt processing(theoretically, higher the packet size, lower the interrupt processing overheads) I got the following readprofile results(I have just included 2 interrupt processing associated fields here, i am not sure if there will be any others!) for two MTUs (and corresponding PDU sizes) at the send side(TCP connection): MTU 13000 - Send Side =================== 94 __do_softirq 0.6963 397 handle_IRQ_event 4.41 MTU 800 - Send Side ====================== 206 __do_softirq 1.5259 741 handle_IRQ_event 8.2333 I see lots of processing overhead due to handle_IRQ_event at the send side. DOes the recieving of acknowledgements trigger handle_IRQ_events??Or does the sending operations also cause these triggers in handle_IRQ_events?? Any ideas are welcome!!
