Is there a limitation to the GT-BE98 Pro Upload Speedtest

[Vager]

Hi,
I'm on a 3Gbps Up/Download Fibre connection through my ISP.

However, it would appear that there's a limitation to the Upload speed on the speedtest. I think it may have to do with the amount of upload streams the router speedtest uses.

I have no issues when doing the speedtest through the 10G port on LAN 6 on my PC using the APP or via the Webgui.

However using the router.. I get these results. I'm using both the built-in App, as well as the addon spdMerlin.

This situation will make a lot of hardware offloads invalid, and with the performance of A53, it may be difficult to handle it.

Not sure what you mean?

These speedtests are run on the BCM4916, so traffic goes through the CPU anyway and cannot be fully offloaded to the ASIC. In this case, the PPPOE offload feature may also have limitations.
Next, if the router Ethernet device implements host interface traffic offload features such as CS, SG, TSO, RSS, etc., it can reduce the burden on the CPU to process packets.
In the worst case, with the performance of Cortex-A53, a result of 1Gbps is not unexpected. From your results, it seems that traffic offload is only implemented at RX.

Don't use the built-in speed test, it's CPU limited. Test with a wired client only. Discussed multiple times.

Thanks, I did try searching, but none of the results that I found, gave me the results I was looking for. I do appreciate your response.

Thank you for your response, much appreciated.
