Hi All,
Just a quick heads-up that I've also just finished loading in (some of)
the DBpedia datasets in to the new Virtuoso 6.1 - all went well and
without problems.
Quick notes / feedback (in-case they are useful)
Server (not exactly high spec):
Single AMD Opteron 2216HE [2.4GHz]
2GB DDR2
Ubuntu 8.04 32-Bit
Virtuoso:
Fresh install
configured to use circa 1.4GB RAM (NumberOfBuffers = 160,000)
Triples Loaded:
47,538,772 (most of the english datasets)
Time to complete:
9974598 msec
Noted:
Creating Checkpoints seemed to slow the process, so would probably
change the frequency of checkpoints next time I Bulk Load.
Overall nice and happy to have a 6.1 installed without any problems
(build and install only took a few minutes, config less than a minute)
and all the dbpedia sets I need loaded in all in an evening with no
problems!
Most pleased :)
