I did some tests against more data around 5GB with 32GB of RAM available.

The query with a cold cache is much faster using guile:

cold cache: 0.027838s
hot cache: 0.023536s

The timings for virtuoso with the same query on first start:

cold cache: 0.744s
hot cache: 0.008s

After restarting virtuoso, I got the following timings for the same query:

first query: 0.058s
second query: 0.008s

In the case the cache is cold, the query is 27 times faster with guile
nomunofu. After restarting virtuoso, guile-nomunofu first query is two
times faster.

Disclaimer: benchmarking is a dark art, take those numbers with a grain of salt.
