It's an UltraSparc, around 1GHz; theoretically 8-way multi-threaded,
with shared L2 cache (IIRC, somewhat equivalent to x86 hyperthreading,
but a decade older technology).

Absolutely. The SunFires, and any other Sparc machines, have not kept up
with the rest of the world when it comes to performance (and "specs" in
general).

Here's the relevant docco:

https://docs.oracle.com/cd/E19076-01/t1k.srvr/819-3245-12/819-3245-12.pdf

You'll note that it says "Copyright 2007" ... not exactly bleeding edge.
