Windows 10: Low intranet transfer speeds between windows PCs using gigabit network

Hello everyone,

I decided to open this thread about a subject which has been discussed widely in different forums on the net, namely the extremely low transfer rates of data between PCs running Windows using a gigabit network, because I think to have observed something which - as far as I see - was never reported anywhere else until now.

So, this post is based on my report here, which i will now republish in a slightly modified way.

I see the same problems many others are reporting, i.e. low transfer rates between two windows PCs (7 <> 10 or 10<> 10) over a gigabit network, my transfer rates are never higher than 25MB/s and go down to a few MB/s in many cases.

However, I did carry out some test using the following software: Downloads | Totusoft

And the results are impressive!!! Testing the transfer of files of 500 MB and 2 GB in size I get up to 800+ Mbi/s transfer rates (in both direction and between all PCs), which is what I would expect from my pc/gigabit-network configuration.

So, if transfer rates up to 800 Mbi/s are possible (this corresponds to approx. 200 MB/s, if I'm not wrong), than the problem cannot be hardware-related but must lie in some windows-related stuff. I did not have this problem with my 3x win7 pc network, only when I installed win 10 on two of these PCs I started to get the limited rates).

For everyone observing the low transfer rates using the windows copy system, please try the SpeedTestSoft I shared above, run it more than one time to get some statistics and please report if you're observing the same stuff as I am.

So, question remains: what is the problem with windows which does not allow the high transfer speeds which are allowed on a hardware level?!

Cheers

computer running windows 10 cannot connect to internet via gigabit switch

After trying to expand the only gigabit port of my technicolor modem router by using the d-link switch failed i then grab the d-link dsl-2770l gigabit modem router to make use of all the gigabit ports provided by the modem instead and of coure the asus still
failed to recognise the ethernet connection (error: cable in unplugged).

So strange both modem router is gigabit (well the D-link ethernet ports are all gigabit whereas only Technicolor only has 1 Gigabit port (GbE) but that is the port I have been connecting the K52F to) but only the one on techincolor modem worked with my
laptop NIC

After many searches on google some one suggest changing the speed & duplex of the adapter so i give that ago and this what i found:

When the Asus reconnect to the Technicolor modem via the gigaport (GbE) on the modem, on the Laptop I went to: Control Panel, Network and Internet, Network connections, Local Area Connection (the ethernet card), change settings of this connection, Configure,
ADVANCED, Speed & Duplex, and changed from:

AUTO NEGOTIATION to: 10Mbps/Full Duplex - WORKED ! and then

100Mbps/Full Duplex - WORKED ! then

1 Gbps/ Full Duplex - WORKED

I then went to: Control Panel, Network and Internet, Network connection, Status, speed is 1Gbps, went to Task manager, Performance, Ethernet the throughput shown is 100 Kbps.

When connect to the new d-link gigabit modem router, changed from:

AUTO NEGOTIATION to: 10Mbps/Full Duplex - WORKED ! and then

100Mbps/Full Duplex - WORKED ! then 1 Gbps/ Full Duplex - nothing, and back to

Auto Negotiation - NO CONNECTION

1 Gbps/ Full Duplex - NO CONNECTION

Back to 100Mbps/Full Duplex, I then went to: Control Panel, Network and Internet, Network connection, Status, speed is 100Mbps, went to Task manager, Performance, Ethernet the throughput shown is also 100 Kbps.

Both speed 100Mbps and 1Gbps give the same through put, 100Kbps so that 100Kbps through put is my internet connection and not data transferring speed between computers on the next work hence no differ whether adapter speed is set at 1Gbps/100Mbps/10Mbps?????

The latest driver available for this adapter is dated back to 2012 so perhaps the driver is so old that it isn't compatible with more update gigabit provided by more modern hardware like one use in the D-Link, worked for the Technicolor because it
uses older hardware?

I assume the K52F is not compatible with gigabit modem router/switch so data transfer between all computers on my network will never be able to connect to the K52F at gigabit speed, 100Mbps max

 

Slow file transfer speeds while copying a file from a windows 10 machine to a windows 7 machine over a network.

Original Title: Slow file transfer speeds

I am getting 1Mb/s transfer speeds when copying a file from a windows 10 machine to a windows 7 machine, both machines are on a gigabit network and are running a 1 Gb/s.

any ideas what may be causing this. it started when I installed my windows 10.

The transfer rate will be limited by the storage location that the file is going to. What is the transfer rate to/from your hard drive?

 

Also, dare I say it, but besides what LCDR pointed out, I'd like to ask the obvious:

Ok, you installed a G router, possibly a G switch (I have both in my network, plus all my cabling is Cat6a (See below)), and zero transfer issues, I doubt it is the OS... but ...

Are the systems ALL using Gigabit capable networking adapters?

You can't expect that kind of transfer rate to begin with if one, or both adapters on the sending and receiving PC are not Gigabit rated as well.

Then it's a matter of mainboard HW - and how the HDD is connected, If SATA, what generation is the drive?

Just because you might have a SATA 6 g/b s rated board means that you'll get that rated speed, the drive would have to be at that rating as well.

Lastly, but less likely, you could have a crappy network cable - Cat5 / Cat5e variants are not rated for the higher speeds of today's rated Gigabit networks, Ensure you have Cat6 variant cables to get the most out of it.

 

RWOne the falicy about Cat-5e has been beaten to death and proven that it can handle up to 2 gbps speeds. Cat-5 has not been around for over two decades.

It is all about LAN to LAN with what networking equipment they are using and what the hardware is on both machines you are transferring to.

There is no such thing as a G switch. Even with a 10 mbps connection, they would still get decent transfers. I have a 1000 mbps network, that is using a Business Grade switch, Router and Access Point. I have zero issues with my network using Cat-5e between the Access Point, the switch and Router. It is all about how good the switch and router/gateway is, in what determines how fast the traffic will go from point A to point B.
