Hi. I have a company gateway that is connected to a 30/30 Fiber connection, network termination point is a MRV OS-904. It acts as a firewall/router for the DMZ/hosts/lans behind. Software: CentOS 6.9, bare minimum install, all latest patches. Hardware: Xeon CPU, Intel server MB with two Intel PRO 1000 (e1000, e1000e) network cards, adaptec RAID, 8GB RAM On the hosts/lan behind I can happily achieve 28.8 mbs - it seems it's being capped at that speed by the provider. However, on the host itself I cannot get passed 820k/s max, even if I switch off iptables and anything else that could interfere with the download/upload bandwidth. I have no idea why this is the case - It only matters when I need to "yum update" as the updates take 4 times longer than on the CentOS DMZ hosts behind it - but yes, its rather annoying! Where do I need to look? What am I missing? Jobst -- Passwords are like underwear.
