Download Speed Slow but Upload Fine Ethernet
Deadening wired upload speed vs Linux on same hardware
Intel® Ethernet Controller X550-AT2, 10G network interface on ASRock Rack ROMED8-2T with AMD EPYC 7232P processor.
Windows 10 Pro for Workstations, 2004.
Latest Windows updates and Intel drivers installed as of 09/09/2020.
This machine is a dual boot, the in a higher place Windows version, and Ubuntu 20.04.
When doing a speed test, I go good performance from Ubuntu, but very poor uploads from Windows. This is on the same machine, the verbal same hardware.
The WAN link is 1000Mbps downwardly, 50Mbps upwards.
This is the Windows speedtest event:
This is the Ubuntu speedtest result:
I have tried to tweak the adapter's avant-garde driver settings in Windows, such as disabling LSO, etc. No luck, functioning remains poor.
I've as well noticed it on another PC running Windows 10 Pro, and a laptop running Windows ten Pro for Workstations, both requite the same poor upload performance. Whereas my other Ubuntu 20.04 Server automobile, and also my phone continued via Wi-Fi, is getting good upload speeds.
I have fifty-fifty taken the Windows laptop and plugged it straight into my incoming WAN connection (bypassing router), and it even so gets poor upload speeds.
Incidentally, when the speed test is running, I can see that the upload looks bursty on Windows, like it is but getting chunks of data here and at that place, while in Linux and on Android information technology looks the same as the download, the graph is drawn at a consistent high charge per unit and with consistent loftier values.
How-do-you-do,
Thanks for posting here.
In general, there are several reasons may cause upload speed deadening.
I would propose you try the post-obit method to run into if the upload speed tin can be returned to normal.
Choice ane
Open up Control Panel > Network and Sharing Center > Change adapter settings > Correct click the adapter that y'all need check > click Properties > click Configure > in Advanced tab, locate to Speed & Duplex > select the value 10 Mbps One-half Duplex > click OK to see if the issue can exist resolved.
Option two
Press Windows+R to open up Run, insert gpedit.msc, click OK to open up Local Group Policy Editor > Computer Configuration > Administrative Templates > Network > QoS Packet Scheduler > right click Limit reservable bandwidth > click Edit > select Enable and set Bandwidth limit to 0 > click Apply and OK
Option 3
Click Start, insert cmd to open a CMD window with administrator privilege and please insert the following command and press enter
netsh interface tcp set global autotuning=disabled
And then in the aforementioned CMD window, insert command regedit to open up Registry Editor
Locate to HKEY_LOCAL_MACHINE\System\ControlSet001\services\AFD\Parameters
Correct click to create a new DWORD Value, Value name: DefaultSendWindow, Value data: 1640960, Decimal.
Click OK and Reboot the machine to encounter if the issue tin be resolved.
Option four
Repeat the first two steps of Pick 3 to open the Registry Editor
Locate to HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Net Settings
Right click to create a new DWORD Value, Value name: SocketSendBufferLengt, Value data: 4000, Hexadecimal.
Click OK and Reboot the machine to meet if the event tin can be resolved.

Option 3 made a difference, now it is around 30mbps (up from around 10). Still non near the linux functioning of effectually 47mbps.

Option 3 did information technology for me. I went from 12Mbps to 400Mbps, which is exactly what I'm paying for and also the same as my download speed.

I have the aforementioned issue.
under windows 10 (latest updates), max upload is virtually 6-7mbps
an android emulator under windows gives me near 30mbps upward
the aforementioned machine booted into Linux is nearly l-60mbps up
iPhone as well clocks in at about fifty-60mbps up and similarly iMac
fastest upload speed recorded (not sure which motorcar), was about 100mbps up, then the link is capable of much higher speeds...
and all are about 80-100mbps download
my internet connectedness is non express or throttled at a certain rate, it is an 8-mile microwave link, and varies a fleck, yet never got any lost packets.
I tried everything in this (and other guides, which give similar instructions) and no change for windows, all the same the android emulator upload is now only 20mbps...
Hi,
if yous accept already tried all the suggestions that take been proposed here to no avail, you can endeavour this path:
Settings> Update & Security> Advanced Options> Delivery Optimization> Avant-garde Options> Download / Upload Settings, movement the slider of the unlike items to higher percentages or according to your needs.
Hi,
Thanks for your feedback.
If the issue still existed afterwards updating settings per above suggestions, collecting network traffics should be necessary for farther investigating. Nevertheless, assay of network traffic is beyond our forum support level. Then I would advise yous contact Microsoft Customer Back up and Services where more in-depth investigation can be done so that you would get a more satisfying explanation and solution to this result.

This is weird. I take just the exact problem. I take a yard/400 fiber to my house and within the country I become the full upload speed, nonetheless internationally I but get around 50-80Mbps on ANY Windows 10 or Windows Server auto. On MacOS or Linux I get the full 400Mbps. This pretty crazy. I dont think latency is any issue as its pure fiber. We are looking in to this likewise.
I am having the aforementioned problem every bit well. I have tried customer back up but I was unable to get through to someone who had plenty network noesis to aid. In the finish the agent said I should get the hardware checked!
I have tested it a number of different ways. I accept an onboard Intel i211 nic, but I've besides tested with a TP-Link USB 3.0 ethernet adapter and also going via my android phone. In all cases the download speed is equivalent to what I can go far Ubuntu on the aforementioned machine, merely the upload speed is nigh 25% of available. I've even tested the speed via the phone and the PC whilst the PC is accessing the internet via the phone. The PC again has approximately 25% of the upload speed of the telephone.
I've tried updating drivers, adjusting all the suggested settings on the adapter, changing the reservation in the registry, using netsh to disable autotuning and fifty-fifty completely wiping the PC and reinstalling Win 10 Pro from scratch. Same results. What is really odd is that the performance on the LAN is superb. I get easily over 100MBps to my file server. This event only hits internet uploads.
It's non my network, I can become full upload speed on exactly the same PC if I boot into Linux. My best guess is that at that place is some behaviour inside the Windows TCP/IP stack or perchance higher that is causing this problem. I'm fairly sure it's higher than the driver level. All I can promise for is that perhaps someone in Microsoft who understands networking sees this and investigates...
few more things to add together:
my wife'southward laptop tin achieve full speeds downwards and up. my laptop under windows 10 but upload is express/restricted/throttled. the aforementioned laptop under Linux Mint full speed uploads, same laptop, with an android emulator under windows 10, and uploads are likewise full speed. in all cases, downloads are full speed.
therefore I can merely assume information technology is a software/operating arrangement/driver result (all drivers are updated using the intel website on an ongoing basis)
I've tried all the suggested settings, registry, etc, no change
Is your married woman'due south laptop Windows 10 also? Did she get the total speed on wired or wifi? Effort wifi on your ho-hum laptop, my Windows PC uploads slow on wired and fast on wifi!

I have absolutely the aforementioned issues!
I am getting on all Win x clients only 4 Mbit upload, just all Linux and Apple devices get 45 Mbit.
Did y'all find whatsoever solution how to prepare that?
Here is the long version of my problem clarification and what all I accept tried. That must be a Win 10 trouble:
Hello,
for about one week I have a very mysterious problem on my Windows 10 PC.
The PC is connected by Gigabit LAN to a Switch and reaches full Gigabit speeds for up- and download inside my LAN (for instance when copying to or from my NAS).
The upload speed at speedtest.net in the new Edge Browser (Version 86.0.622.63) reached around 1 week ago everytime the full 40 Mbit, but now but 4 Mbit.
I did not alter anything and nevertheless reach full ane Gbit speed inside my LAN.
The cyberspace connection has constant 40 Mbit upload and varies only minimally. All other clients (MacBook Air, iPhones, Apple TV) are still reaching the full 40 Mbit, no matter if they are continued by LAN or WIFI.
I think that the trouble came because of a Windows 10 update or driver problem and will bear on more users.
The strange thing are the constant different speeds on the same PC in different browsers / apps:
- Edge: 4 Mbit Upload
- Firefox: xx Mbit Upload
- Speedtes.internet App / CLI for Windows: 20 Mbit
The results are the same if I connect the PC directly to the router or to the switch.
If I boot the PC under Linux, I become the full xl Mbit in every browser, even the new Border for Linux.
I tried all that things already and cipher helped:
- New Beta- and Dev-Versions of Border
- Resetted Windows network and firewall settings
- Replaced network cable and used another port on the switch
- Resetted the router to factory defaults
- Installed completely fresh Windows 10 and formatted the SSD completely. I tried version 1909 and 20H2.
- New network cards: TP-Link TG-3368, Intel Gigabit CT Desktop Adapter, USB 3.0 to Gigabit-Ethernet-Adapter. The commencement ane was an Intel I219-V OnBoard on the Asus Z170 Pro Gaming mainboard.
Everywhere the same problem. Upload stucks at 4 Mbit in Edge. Even after re-installing a fresh Windows.
I also installed Windows 10 with Bootcamp on the MacBook Air and have the aforementioned bug at an also completely fresh installation.
I don't empathize it anymore.
I think that Microsoft produced a bad bug hither anywhere, cause the same Hardware is working under Linux with full 40 Mbit upload and likewise all other non-Windows-clients do reach the full forty Mbit everytime.
I idea that possibly some Windows settings were screwed upward, but the same problem appeared on completely fresh Windows installations.
Practise you have any idea how to solve that, or exercise you see similar issues?

Thanks for the suggestions, unfortunately no luck:
- I'yard using Microsoft'south Windows Defender, not a third party product. And disabling Defender (virus protection and firewall) had no effect.
- Also did a clean boot (only MS services enabled), no effect.
I've added some more info in my original post, FWIW.
