Unfortunately not very useful benchmarks.
They were done using the official image, which is a snapshot of Debian. Over one year old.
The ecosystem has advanced significantly since, to the point where several programming languages that only had an interpreter are JIT now.
Ancient gcc aside, the Debian snapshot was built for RV64GC (2019, unchanged since 2017). This means it doesn't leverage the Zba/Zbb instructions the SiFive U74 21G1 CPU has. They are critical to performance.
The official image's kernel itself has barely changed since the board launched, doesn't reflect the progress made by the upstreaming effort[0].
e.g. that kernel doesn't even have the cryptography acceleration patches. This is compounded with not using the aforementioned bit manipulation instructions, themselves very useful to cryptography.
To top it off, a heatsink was not added to the VisionFive 2. This means it'll have overheated and throttled on most of the tests[1].
These benchmarks do not reflect current performance and can be dismissed outright.
I am looking forward to seeing this board (or any JH7110 board) benchmarked with current software and adequate cooling.
