Hi Riccardo, Interesting. Unsure if Hardinfo2 is ported or builds on a BSD based distro. If so, you may want to give it a try. Hardinfo2 has some interesting benchmark tests. Some benchmarks based on my various Linux based systems. https://pastebin.com/raw/eptnLerq Hardinfo2, source code: https://github.com/hardinfo2/hardinfo2 Regards, Tony On 10/16/25 10:49 AM, Riccardo Mottola wrote: > Hi! > > just to share a comparison, now that I upgraded my Ultra2 to 10.1 I > can compare "apples with apples". > > How does a Netra T1 compare to Ultra2? > General setup is similar.
