Hi, I am seeing very strange behaving for l2fwd in VM, here are performance number:
64byte -- 8.4 mil pps 256byte - 7.7 mil pps 512byte - 1.5 mil pps 1500byte - 500K pps My setup details are - Traffic coming in on a 10G interface and going out on another 10G interface - Both 10G Nic are 82599 - using virtual function in VM(vmware esxi 5.1) - Host OS: Ubuntu 12.04 - Using one cpu to do these testing So my question? Why packet size bigger than 256 cause performance drop a lot? Thanks, Bin
