    Disabling “Large Send Offload (LSO)”

    Large Send Offload is a technique of improving network performance while at the same time reducing CPU overhead. Apparently it does not work very well, so it was suggested to disable it. If you would like to know about LSO, check this MSDN article from 2001 (Task Offload (NDIS 5.1) (Windows Drivers)).

    LSO is an option located in a Device Manager under your network adapter, so this solution requires Administrator Privileges.

    Follow these steps:
    1.Open Start Menu, right-click on Computer and select Properties
    2.Under Control Panel Home located on the left side of the window click on Device Manager
    3.You will get a list of all devices on your machine. Expand Network Adapters.
    4.Find your Network Card and double-click on it.
    5.Select Advanced tab. You will get a list filled with different options.
    6.Select Large Send Offload V2 (IPv4) and set the value to Disabled
    7.Do the same for Large Send Offload V2 (IPv6) if it is available
    8.Click OK

    After clicking OK, tried to send a file over the LAN network. Transfer speed started very slow, but it was gradually picking up speed. Decided to restart the computer and try to send that file again and this time it worked like a charm.

    Now that sending of files worked as it should, also checked speed for receiving files. It turned out that it was still slow but all that was needed to fix was to disable Large Send Offload V2 on the other computer. Once done, problem was solved for receiving files as well.

    Hope this works for you guys / girls
    Thanks for this suggestion. My Windows 10 Pro's network will slow down to 240 Kbps according to Fast.com. A reboot always brought it back to around 85 Mbps. I have just altered this setting as a test.

    Sadly after an hour or so my network has slowed down again, even with this setting.

    Thank you! I also created an account just to say that this worked for me - and selecting 9014 bytes for Jumbo Packet size (instead of "Disabled") helped as well. I was getting intense skipping and pausing on my media players playing audio files from my NAS (not a problem on Win7) and these things fixed it for me. In fact, navigating folders on my mapped drives on the NAS has never been this fast. Thank you!

    So much for saying, that 10 works out of a box, we will always need utilities like TCP Optimizer.

    Well seems my problem has nothing to do with Windows 10. The problem seems to be with Chrome or the Fast.com web page. I was using Fast.com to check on my ISP connection. If I open a brand new chrome window I always get over 80 Mbs. If I leave chrome open to fast.com and retest later the results fall to 270 Kbs.

    Jumbo frames will only work if set to the same value on each device, so you would need to set it on your NAS and also you will need a fully managed switch and set your PC and NAS ports to use jumbo frames. only setting it on your desktop will make the packets fragment back to 1500 bytes, having a decent setup (good NIC in desktop and a speedy NAS) and using jumbo frames will get you close to the limit of 1gbps network, i get around 123MB/s network transfer speed, theoretical max is 125MB/s but you have to take into account overheads so you would never get 125MB/s

    As long as the Router/Switch you are using ALSO is capable of JumboFrame Packets. Many TP-Link Routers and switches don't for example eg my Archer C7 , while my computer and NAS can.

    Windows 10 32 bit

    I am having the SAME issue as everybody else EXCEPT I DO NOT have a "Send Offload V2 (IPv4)" or a "Large Send Offload V2 (IPv6)" in Network adapters OR in ANY advanced tabs, the ONLY thing in there is Intel(R) 82567LM-3 Gigabit Network Connection & the only thing in advanced 'Flow Control', 'Packet Priority & VPN', 'Speed & Duplex', 'Wake on Magic Packet', & 'Wake On Pattern Match. There is nothing Offload anywhere in Network Adapters.

    I'd hate to be that one guy, the only guy, but these instructions do not work for me! My Windows 7 Machine, same exact model (Dell Optiplex 780) does not observe this problem. And these are two identical machines.

    2 different driver versions ? try an Intel Full Driver if it is using a Win10 Update installed driver ( or possibly a Dell stripped Driver?) to get all options back perhaps , at least on my Intel 218 the two drivers are quite different in Device Manager. Win10 is enforcing Signed Drivers now though so that can be a Pita , it is telling me Intel's latest Drivers on their Website are not signed and won't allow something to start, so I went back to my MB CD driver.

    I'm afraid I'm going to have to say that not only did this not speed up any file transfer rates on my LAN, but in fact caused any machine on which this was disabled to become inaccessible to my network.

    I realize that this is an old post, but in having my own problems, and then finding the answer for me, I thought I might add my solution to those above. So I was trying to copy 103 kb files over to a mapped network drive and it was taking 3 min or longer for each file to be copied.

    SOLUTION: I was able to determine that the files that I was trying to copy over had an ADVANCED ATTRIBUTE of "Encrypt contents to secure data". So I selected all the files, then right-clicked, chose "properties", then clicked on ADVANCED..., then unchecked the box "Encrypt contents to secure data". Problem solved! Lighting fast copies. BOOM! [MICROPHONE DROPPED]. I hope this helps someone in the world (just 1 of 7 billion).
