Actual measurement of Qunhui 71000 Gigabit Network

For a better browsing experience , Welcome to Hardworking Kelsen's personal blog http://nas.hepcloud.top:7000

One . explain

1. Qunhui must have a 10 Gigabit network card ,windows11 There must also be a 10 Gigabit network card .

2. Qunhui network settings MTU Jumbo packet .

3.windows11 10 Gigabit network settings , Add Jumbo packet settings , And the Internet ip With Qunhui ip Below segment .

4. Mechanical hard disks use multiple , Eight plates work better , If only one mechanical hard disk is used , No matter how high it is, it can only reach the upper limit of mechanical hard disk 200M Up and down .

5. If only SSD Reading and writing , There will be SSD cache , The cache will run out of speed .

Two 、 Qunhui configuration

In the group light DSM Set up MTU by 9000, The specific path is ： Control panel – The Internet – Network interface – edit – Manual settings MTU.

3、 ... and 、windows11 Set up

Control panel – The Internet and Internet – Network and Sharing Center – Click Ethernet 6( This is our 10 Gigabit network card ) – attribute – To configure – senior

Link Speed Set to 10G

Jumbo Packet Choose the biggest 16348Bytes

Flow Control choice Disabled

[ Failed to transfer the external chain picture , The origin station may have anti-theft chain mechanism , It is suggested to save the pictures and upload them directly (img-Pytv1R01-1658198742291)(http://nas.hepcloud.top:6391/images/2022/07/19/10GB-04.png)]

Synology NAS Of IP and windows11 Of IP In the same IP Below segment , Such as my NAS yes 192.168.31.98,windows11 Of ip yes 192.168.31.190, The first three are the same .

Four 、 install iperf3

5、 ... and 、 Use iperf3 velocity measurement

The download address of the client ：https://iperf.fr/iperf-download.php

After decompression CMD Run in mode

C:\Users\Jason\Downloads\iperf-3.1.3-win64\iperf3.exe -c 192.168.31.98 -t 20

The front is after decompression iperf3.exe The path of ,-c Specify Qunhui ip by 192.168.31.98,-t 20 Specify the test 20 second . The speed can reach 10 Gigabit .

iperf3 Command parameter description

-c     Means to start as a client , And fill in the server's  IP  Address ;
-p     Specify port number , It needs to be consistent with the port number specified by the server ;
-t     You can specify the duration of the transmission test , Iperf  Within a specified time , Send packets of the specified length repeatedly , The default is  10  Second .
-u     Specify the test  UDP  agreement ;

-i     Set the time interval between each report , The unit is in seconds , If it is set to a non-zero value , The test report will be output according to this time interval , The default value is zero ;
-f     Specifies the bandwidth unit ;

-J     To output  JSON  Format test results ;
-R     Reverse transmission , default  iperf3  Use upload mode ： Client  Responsible for sending data , Server  Responsible for receiving ; If you need to test the download speed , It's in  Client  Side use  -R  Parameters can be ;

6、 ... and 、 Data copy test

NAS Copy data to windows11 Actually measured , The data is 33G The original movie file ：

The speed of copying data is about 700M The appearance of

from windows11 copy to NAS Hard disk speed , It can also be maintained at 670M Up and down , Don't lose speed in the whole process .
