My PC has a network card or a Realtek 2.5GbE Network card. For a long time, I am using the network driver provided by Microsoft, which is from Windows 11.
Recently, I think I can try the Realteck official driver, and see how much difference.
Setup testing environment
iperf3 server is a NAS, with a Gigabit connection to the Switch, TP-Link TL-SG3210XHP-M2 Network Switch.
From the Switch to a AP, is a 2.5GbE connection.
iperf3 client is my PC, with a Realtek 2.5GbE card, with a Gigabit connection.
Before
Here is the iperf3 testing result, based on the current driver 10.56.119.2022, dated 2022.01.19.
The bandwidth is 880Mbits/sec.
Update the driver
I checked the official Realtek website and the download page
I download the Win11 Auto Installation Program (NetAdapterCx) driver file.
Then, install it.
The latest version of the network driver is 1125.7.318.2022, dated 2022.3.18.
After
I run the test again.
The Bandwidth is 949Mbits/sec
It is about a 7.8% improvement in performance. I did nothing, but upgrade the driver of my PC and with all default settings.
