So, an update: I discovered this thread[1] and this one[2] and tried 
rebuilding ruby with -O3 and --disable-pthreads, and things have got a 
bit better.

My benchmark test now takes about 1.2 seconds.

However the benchmark from [2] takes about 44 seconds, which is 
appalling in comparison to the scores from similar machines on that 
thread.

I have very little idea what I'm going when building things from source, 
but I feel as if I'm on to something here. Any pointers appreciated very 
much.

Nope, that's comparatively really quick, like 0.3 secs max.
