This is God's work. Unglamorous but useful

It is frustrating how poorly STH handles their networking reviews, their testing methodology is apparently a secret. Benchmarking is really fucking difficult to get right and STH makes it very hard for the reader to know what they are testing.

Looking at the Wiitek 10Gbase-T adapter review:

We also received requests to test jumbo frames on these modules so we have started to do that. Here you can see the large packets passing even though we are using the -f switch in our ping command.

First of all, if you didn't crop out the command, you wouldn't have to explain that. Secondly, what does that even mean? The -f switch on Linux is flood ping; I don't know what you are doing here so I have to go look that up in the Windows documentation to figure out that it's "do not fragment". I'm not surprised, but why didn't you just say that? I would argue that if a reader doesn't understand "do not fragment", they won't understand what the -f switch does anyway.

EDIT: The 6COM, QSFPTEK and ADOP reviews each claim to be "using -d -l 8972 in our command line" which I am sure is a typo of -f, but the above complaints still apply. Maybe you can infer the meaning, but -l is not length on Linux. Just use plain English and keep the command in the screenshot.

We ran a few NAS tests to a SFP+ SSD NAS from a workstation with a 2.5/5/10Gbase-T adapter as well as a SFP+ adapter to see the impact of the Wiitek SFP-10G-T has running in a MikroTik CRS309-1G-8S+IN switch.

This is the testing methodology for the performance test in its entirety. No word on tools used, no indication whether jumbo frames are in use, no mention of the capabilities of the two systems (the reader doesn't know if the NAS and the workstation can do 10 Gbps at all). Why even test against an SSD instead of RAM? I'm not saying doing so is wrong, but they don't even attempt to explain or discuss their choices.

Here we see virtually identical performance to the Ipolex, HiFiber, FiBay, Mikrotik, and FlyFiber units [...]. It is also slightly faster than the three units that did not support Nbase-T speeds. Differences, however, were within +/- 1% of average which is usually a margin of error.

That is the result analysis. No mention of the fact that they are achieving only 6.4 Gbps or why. Actually that is a guess on my part, because the graphs do not contain any numbers. Someone requested numbers a month earlier in the 6COM review, but it seems no one reads the comments. The results for the SFP+ adapter aren't shown anywhere in the review. I had to check each of the previous 10Gbase-T adapter reviews to find out that they did test it in the Mikrotik review and that it outperforms the 10Gbase-T adapters by ~5%.

The Wiitek review doesn't reveal the power consumption of the adapter either, only the final comparison article linked by OP has that information.

Another example is the CableCreation USB 3 Type-A 2.5GbE Adapter review where the comments ask about OS support, CPU utilisation and network latency. No response from STH.

Hey the ioplex one I bought almost a year ago was on here and did very well, nice.

Hello, I am ADOP from Amazon. I am glad to see our products in your evaluation and comparison video. We have been promoting our products in the Chinese market. In recent years, we have only promoted our brand overseas. We want more users to know us. , I have compiled a functional application about 10Gbase-T related specifications, if you are interested, you can find out, and I hope we can communicate with each other about network communication issues, and look forward to your reply.
