Hi there,
I recently added a Intel X550-T1 NIC to my Windows machine. Now after doing some tests I noticed the throughput is only about 2.5 GBits/s (using iperf3 for testing).
Same test performed using an Ubuntu Live Boot Stick yielded me a throughput of about 9 GBits/s.
Things I tried to improve:
- Completely re-installed Windows
- Installed the latest driver for the X550-T1 (from the Intel website)
What as well catched my mind: If I run the test with the loopback interface (localhost) as the target server, I only get the same poor throughput of about 2.5 GBits/s. All my Debian VMs and as well a Windows Server 2019 VM (on an ESXi host) are showing between 40-100 GBits/s in the same test. I as well booted from an Ubuntu Live Stick and was able to get 10Gbits/s here. So it definitely must have something to do with Windows itself.
Can anybody help me out please?
Best regards
