Trying out a specific machine:

1 billion triples : BSBM-1000 (1,000,253,325 triples)

tdb2.tdbloader --loc DB2 bsbm-1000m.nt.gz
Time: 3,218.82 seconds (53mins 39secs)
Rate: 310,751 triples/s

The machine:

Dell 8950, Intel® Core™ i7-12700K Processor
  8 performance cores with hyper threading
  4 Efficient-cores
  Total : 16+4 threads

64G RAM DDR5, 2 memory channels
m2 SSD (1TB)

The database is 191GBytes

4 threads were running at 100% and they were spread across cores (other threads were doing I/O and general housekeeping).

The OS didn't apply any thermal controls - the active threads weren't being moved across cores, the CPU temperatures were only around 44C, and the processor fans wasn't elevated.

The machine was usable during the load.

On the same hardware tdb2.xloader achieved 87kTPS and a database of 132Gbytes
