Thank You Jack i'll keep it at 2048 now. I have plans to add two more igb interfaces. Should i decrease values to 1024 in case i will have four interfaces in server?
I found there are additional tweaks for igb card available: hw.igb.enable_aim=1 this one enabled by default and i understand its meaning Where can i read about the rest? hw.igb.low_latency=1000 hw.igb.ave_latency=2000 hw.igb.bulk_latency=4000 hw.igb.rx_process_limit=400 hw.igb.fc_setting=0 hw.igb.lro=0 Some years ago i downloaded an article about em card from intel site. Perhaps there is one for igb as well?
