It is the reverse - GSO will segment one super-packet just before calling the driver so that the stack is traversed only once. In my case, I am trying to send out multiple skbs, possibly small packets, in one shot. GSO will not help for small packets. > Btw, main CPU limiting factor here is syscall overhead (userspace protocol > processing with 1500 MTU allows to reduce CPU usage and increase > performance for 128 bytes packets sending/receiving total of 10 times). I will test this also. But I was curious to see if without any changes to applications, I can get better performance by linking packets and sending it once to the driver.
