Problem with 10Gbps network card AQC107
Problem with 10Gbps network card AQC107
Hello. The problem appears to be with your Windows 10 setup. When using Ubuntu Live on your PC, speeds drop significantly—9.9Gbps versus 3.5–4Gbps on Windows 10. A clean install isn’t feasible at the moment. Consider checking network drivers, disabling background apps, or testing with a different OS if possible.
Which standard is being used? Iperf displays network throughput metrics. The source can be verified by running tests on a RAM disk.
Hello! The connection via SMB appears to be around 3.5-4Gbps, consistent with Iperf results. However, when loading from an Ubuntu Live CD, the speed jumps to 9.9Gbps. This suggests a potential issue with Windows 10. You're using a RAID1 setup with two NVMe Samsung drives.
Wow, I'm facing the same problem too. It stopped working at 3.5-4gbit even on Windows. I'm still trying to figure it out.
It hasn't been long since I last worked on it, but I haven't taken any action. I plan to revisit it next week and share my findings here! Also, just a note: your Asus C100C and Intel X540-T2 are connected via the Netgear XS508M Switch. Have you configured MTU to 9000 or enabled jumbo frames on all devices?
I've encountered this on both my Windows PC and Unraid server using AQC107 network cards. The issue seems tied to Windows, as Ubuntu runs smoothly at 9.9Gbps. I tested multiple streams with the P8 flag in iperf, which returned 9.8Gbps—unusual since single streams are slower. What’s causing this discrepancy?
Hey there, sorry for the delayed response. I tried it on Ubuntu Live and got around 4-8gbit, averaging about 6-6gbit. That's roughly 50% better than my Windows file transfers. With four connections I reached 9.4gbit, which matches what I expected. It seems Windows isn't using the connection well. I'll test iperf again on Windows and update this post. Update: same result on Windows. Single stream gives 6.8gbit, multi-stream up to 9.4gbit. Even with -P2 only 6.8gbit, but 3 gives 9gbit. Update: using the Freenas as client, I get a bit faster 7gbit single and still 9.4gbit multi. In theory everything functions. Update: actual file transfer from PC to NAS is 6.6-7gbit with one, two, or three simultaneous transfers—no difference. From NAS to PC it's 3-4gbit regardless of how many files are sent.
