Speed issue

[kdulep]

i have jumbo frames disabled and iperf3 runs fine without driver – true 10gbit

and after installing driver speed drops to 1.7 gbit

also there a few filters (adguard/adguard vpn symantec) on system that doesn’t affect 10gbit

 

thanks for quick reply

I have tested the driver with several 10 Gbps network adapters and have not observed any noticeable performance degradation. One example is the Broadcom P210tep NetXtreme-E dual-port 10GBASE-T PCIe adapter.

However, 10 Gbps networking is still relatively niche, and hardware and driver implementations can vary significantly. To provide a universal packet-processing interface, Windows Packet Filter disables NIC task offloading features; jumbo frames are just the most commonly discussed example. This may affect different network adapters and their drivers in different ways.

The drop from 10 Gbps to 1.7 Gbps is unusually large, so the issue may be specific to the Marvell AQtion AQC113 driver or its interaction with other network filters installed on the system.
