10G networking

[Matt997]

Hello All, 

 

So, I am only able to get max 600MB/s Transferring files from one PC to the other. I have looked at everything i know and i just can't figure it out any help. They connected threw a TP-Link TL-SX3008F Switch with 10G SFP+ and OM4 fiber.

Your theoretical max on a 10Gbps network should be 1.1GB/s.  There are some performance issues with SMB file transferring, refer to this article for various things to test to see if Windows is just getting in the way:

Thank you for the information. 

 

My results are as follows

 

Download-PC is Computer #2 and C:\ Test is computer # 1

 

robocopy /J "\\DOWNLOAD-PC\Downloads\Source" "C:\Test"

I even tried to change the MTU on each computer but when i moved it from 1500 it would not work at all it made it slower.  I did a test on the drives and believe they are ok the results are as follows.  Any suggestions.

Using a file transfer to test your network speed will only go so far, when you start working with 500MB/sec + speeds there are many factors that can be limiting the speed.  Your hardware is likely working as expected, it is just very hard to get 10gbit speeds going from Desktop to Laptop on a single SSD.   You would probably need RAID0 SSD's and to have multiple transfers going at the same time..  not just a 2 file robocopy.

 

My guess is the SMB traffic on windows 11 is encrypted so your are limited by the CPUs ability to encrypt the data and send it over the network.

If you really want to find out what is the bottle neck you can try looking at task manager on both computers during the transfer.  Look at the CPU usage (per thread, not overall) and Disk active time on the SSD

 

I would recommend you just use the network and stop wearing out your ssd's with speed tests
