Hello list.

I did a few tests to see how this hardware performs in one of my use
cases (building and testing of a C project in 32 different variations).
Nezha D1, which is a smaller RISC-V board, takes between 4 hours and
5h30m to complete the job using 1 CPU core and populated ccache,
completely on tmpfs.

gcc91 with lesser use of tmpfs took 2h27m on 1 core and 2h12m on 2
cores.

gcc92 without tmpfs took 1h45m on 1 core and 1h33m on 2 cores.

So for this particular workload StarFive seems roughly 2 times and
Unmatched is roughly 3 times faster than D1.
