Windows 10: Slow network throughput on windows 10

Anyone else noticed slow network throughput on 10?

I am running gigabit Ethernet (via cat5e cable) and I can only get about 3MB/s copying local files from my pc to my NAS.

One windows 7, with same hardware, I was getting about 50-60MB/s

Any ideas?

It pretty much is making windows 10 unusable for me.

I am on Build 9860

How Do I Interpret the Throughput Value on Task Manager Ethernet Graph

Task Manager on the Performance tab / Ethernet selected shows a Throughput value. This is at the top right corner of the box containing the moving graph. At idle I a Throughput of 100Kbps. My link speed is 1Gbps as shown by the LEDs on the NIC card. When
I right click the Ethernet graph and select Network Details the Link Speed is 1Gbps and Network Utilization of 0%.

So what is the meaning of the Throughput number at 100kbps? I can see small spikes on the graph about every 1 second. The Receive number in the lower corner shows 16kbps flashing about once a second. So clearly there is little network traffic. I assume Utilization
is 0% because very few bits are being received every 1 second and it appears nothing is being sent. So my question about the Throughput number. Is it simply the vertical scale of the Graph? If that is so then calling it Throughput is misleading.

What does the Throughput number represent and how is it calculated?

Meaning of secondary line on Windows 10 Task Manager Network graph?

Hello,

Can anyone explain to me what is the meaning of the secondary line (and value) seen on the Windows 10 Task Manager Network graph (highlighted in yellow below)? Is this some kind of 'effective' throughput, as opposed to theoretical throughput? I can't seem
to find any explanation online.

 

Hi there

For some reason I was getting a similar drop in performance when using video streaming from PLEX to a smart Blu ray player - both server (computer) and Blu Ray box on Wired Lan.

I got faster Video transfer when I switched the server to a LAPTOP using WIRELESS - got decent fast Intel wireless card and the router handles the latest wireless technology (802.ac 1.2 GB/s). With the Lan it drops to around 4MB/s -- Go figure !!!!!!!!!.

On W8.1 the Lan operates at nearly 2GB/s so something is hosed up !!! Still it IS a test build.

Running as a REAL machine not as a VM -- note if you "Virtualise" the OS then your throughput will be reduced if using the "Virtualised NIC" rather than a physical one -- this is where HYPER-V probably is a better option if you are running W10 as a VM and want to use NAS with it.

This might have nothing to do with your issue but one thing I noticed on several installations on both real and virtual machines is that an 9841 upgraded to 9860 was / is slower in almost every aspect than a cleanly installed 9860.

 

I suppose I would like to ask what Network Adapter you are using and what driver is it using as far as one from Windows 10 or the OEM?

You are using an Apple system?

 

To the OP. Did you ever resolve your issue? I have the same problem. Gigabit wired connection, only writing at around 2 MB/s to my NAS whereas my Windows 7 Desktop will write at around 30 MB/s.

From Device Manager, my NIC is an Intel(R) 82567LF-3 Gigabit Network Connection. The only setting in its advance tab that is not enabled is "Adaptive Inter-Frame Spacing". I have no idea what that is.

Currently on build 10159.

 

I have the same issue with Windows 10 running slowly I have an Asus TP500L, which is less than 12 months old and uses Mediatek MT7630E WiFi adapter. A simple ping test shows that approximately every 10-20 ping the time increases dramatically from around 23ms up to in excess of 1000ms, this seems to be regular. I have another laptop with windows 7 installed and the ping to the same IP (google.com.au) remains a consistent 23/24ms.

I note that all browsing runs slow, with long hang times during page retrieval.

Is this happening to most users and has anyone found a fix for this as yet?

Cheers

Slow Network drive access prevents using windows 10 in my environment. One TB of data in 100,000 folders/files managed by Windows 2008 R2. Access is from 30 desktop computers on same LAN. Changing any one of the Windows 7 desktops to Windows 10 results in extremely slow access by the Windows 10 computer.

Note: Am able to restore normal access speed by disabling UAC.

Hoping Microsoft will address issue

 

This seemed to work for me:

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

 

Made an account to chime in -- this worked for me. Speed jumped from ~3.0 MB/s to 30 MB/s.

Thank you very much

 

======================
I have a 1Gbs LAN. Using Windows 8.1 Professional I was able to achieve (about) 100MB/sec speed to my Synology NAS. With install of Windows 10 Professional, speed dropped to (about) 10MB/sec. This article helped get file transfer speed back up to (about) 100MB/sec. Thank you, thank you.

 

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. *really
