Guest Sabo, Eric Posted October 10, 2007 Posted October 10, 2007 We are connecting to a 1 GB ports, the highest throughput I am seeing using a 32 K TCP Windows Size (32,768) using Iperf to test is about 530 MBytes per second. Is this good or should it be more than that. I know that ethernet you cannot use 100% on it. We are using broadcom gigabit adapters with Cat 6 (HP and Dell) using a Cisco 6513 switch/router. Does any have an suggestion to any registry settings that might help throughput? On our backups across our network, (1 GB port and same vlans) the average we are seeing is the following: 740 MB/Min Any thoughts? Thanks, Eric Sabo
Guest Mathieu CHATEAU Posted October 10, 2007 Posted October 10, 2007 Re: Gigabit Throughput on a windows 2003 Hello, just to clarify, it's Mbit/s not MBytes. Do you have the latest driver ? Did you raise network driver send & receive windows ? For backup purpose, you ofter have one server and many clients sending their flow at the same time. Raising the receive window in the network's card property made our speed backup much greater. -- Cordialement, Mathieu CHATEAU English blog: http://lordoftheping.blogspot.com French blog: http://www.lotp.fr "Sabo, Eric" <sabo_e@cup.edu> wrote in message news:%23BOYu92CIHA.748@TK2MSFTNGP04.phx.gbl... > We are connecting to a 1 GB ports, the highest throughput I am seeing > using a 32 K TCP Windows Size (32,768) using Iperf to test is about 530 > MBytes per second.

Guest Sabo, Eric Posted October 10, 2007 Posted October 10, 2007 Re: Gigabit Throughput on a windows 2003 Yes, the latest drivers are being used. TcpWindowSize 32768 Tcp1323Opts - 2 NumForwardPackets 60000 ForwardBufferMemory 80000 TCPAckFrequency 13 - was set on the NIC interface Do you see any registry changes I need to adjust? There are really no articles that say do it this way.
