It generates a GUID (and no, I do not want to turn this in a discussion
about GUIDs). As in the Java code comment: it is not the generation of
the GUID that is the problem (that is, I can generate millions of them

It is actually the shortest piece of code that gives me a poor
performance. The conversion problem is much, much larger and much much
I suspect that either my hardware is to slow (but then again, see the
specs), or my Debian is to slow, or my PostgreSQL settings are wrong.
But I have no clue where to begin with determining the bottleneck (it
even may be a normal performance for all I know: I have no experience
with converting such (large) database).
