Windows 10: Slow network throughput on windows 10

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.

 

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]*Cool. I hope this helps someone in the world (just 1 of 7 billion).

 

I have three pc's on my home network. One had windows 10 from the factory the other two were Win 7 and 8.1 and all were experiencing 70-90MB/sec file transfer speeds. My internet was and still is 60MB/sec. After upgrading to windows 10 the file transfer speeds went to 5-8MB/sec. Internet speed is unaffected. I have followed many forums and tried every suggestion and nothing has resolved this issue. The last big windows 10 update did slow down the native windows 10 machine from 70-90MB/sec to 50-60MB/sec. Also, the native Win 10 machine is connecting via wifi and others via ethernet (wired)
Any new ideas? Yes, latest drivers. Yes, Large Offload is disabled and many other suggestions.
