I have uninstalled my Network Adpater and installed it again, and i have reset all network settings using following commands on CMD

ipconfig /flushdns
nbtstat -R
nbtstat -RR
netsh int ipv4 reset
netsh int ipv6 reset
netsh winsock reset
.
And i have put Large Send Offload V2 (IPv4) on disabled and enabled
did a clean boot still not works
i dont know what to do i didnt have this problem before i get full speed at Linux but not Windows 10.

Hello @Fok Pornkaew ,

You may find that your Internet connection is "reordering" network packets (i.e. the packets are not delivered in the sequence in which they were sent; a small amount of change in the order happens as the packets pass through some network devices. The algorithm for coping with this situation is better in Linux than it is in Windows 10.

This long thread describes the same problem: https://learn.microsoft.com/en-us/answers/questions/330172/extreamly-slow-upload-speed-in-windows-all-other-o.html

There are improvements to the TCP/IP implementation in Windows 11, but that still has one or two bugs/omissions which limit upload performance in the face of packet reordering.

If you want to make a small network trace of a slow upload and then share the trace data, I would take a quick look at it to confirm this diagnosis, but I am fairly sure that this is the explanation of the performance that you are observing.

Hello @Fok Pornkaew

Modern Linux file systems (ext4, ext3, Reiser, etc) are very efficient with fast file access. Linux uses a separate partition as swap space independent of whatever file system you choose to use. Linux only loads processes that are required for whatever is running now. This is the reason for the difference in the Internet speed of the operating system.

If you have low Internet speed then you can try to troubleshoot them but comparing might not help you out here for the above-explained reasons.

Hope this resolves your Query!!
