Slow upload performance with CCR2004-1G-12S+2XS

Sun Nov 08, 2020 2:38 pm

Recently I upgrade to 4Gbps broadband and I used the CCR2004-1G-12S+2XS as router.
Here is the network architecture.
ONT-----CCR2004-----Mellanox 6012------PC(Windows 10, 1Gbps Intel 212 on motherboard and Mellanox MCX454A-FCAT at 40Gbps)、Mac(Hacintosh, Intel 10Gbps)、NAS (Linux, 40Gbps Mellanox CX354A FCCT)

By testing via Speedtest, downloading was around 3000Mbps, but uploading was weird.
It was only 120Mbps on my PC and 600Mbps on my Linux NAS, while it could reach 2800Mbps on Mac.

I also tested the Intel 212 adapter on PC. It reached 900Mbps on uploading without any issue. The file transfer from Windows 10 to NAS was 20Gbps.

I tried to remove the CCR2004 and use the ONT as the gateway(router), the uploading speed on PC and NAS are more than 2000Mbps.

It seems to be something wrong between CCR2004 and mellanox adapters? Please advise.

Here is my export.
