Also, tdbloader2 seems to be gradually slowed down from 100k triples/s to
< 1000 triples/s on a normal disk drive by random access after ca. 10 million
triples. Is this unavoidable? I made this change to tdbloader2 but I think it
is not relevant during the data phase:
- SORT_ARGS="--buffer-size=50%"
+ SORT_ARGS="--buffer-size=2048M"
I have tried with Jena 2.13.0 and 2.11.1.
What's the machine it's running on? OS?
As this is the data phase, tdbloader2 is, roughly, streaming the parser
to disk, allocating nodeids (which is a bad access pattern). What size
are the node-related files?
Does tdbloader do better? (sometimes it does, sometimes it doesn't).

Yes.
