I've a system Linux based on ppc8280 platform with unstable performance from a compiling to another. I've a board with 2 Ethernet interfaces and I inject traffic in one of this and analyze the number of packets that I receive in the other one. I obtained 60000 pkt/s the first time, the second time i recompiling the kernel just changing some died function that is not involved in the flow of the packet.In that case I obtained 47000 pkt/s and it seems that moving code position change the behaviour in term of cache functionality. Could someone help me to understand this strange situation
