Much Ado about Arm and Benchmarking

Duration: 16:46

It's not always easy. But at least I'm learning!

If you want to read more about what happened in my HPL benchmarks on the Radxa Orion O6 and Minisforum MS-R1 with the Cix P1, read the following issues:

- https://github.com/geerlingguy/top500-benchmark/issues/54#issuecomment-3518813579

- https://github.com/geerlingguy/top500-benchmark/issues/82#issuecomment-3514084323

And I've since updated my blog post with the new HPL performance and efficiency numbers: https://www.jeffgeerling.com/blog/2025/minisforum-stuffs-entire-arm-homelab-ms-r1
