Hi,I'm in the process of importing the freebase into a local instance of virtuoso 7. I've split the freebase dump into chunks of 10 million triples each.
I'm running two instances of bulk loaders on a quadcore machine with 48 GB of memory (set 4500000 buffers and 3300000 dirty buffers in virtuoso.ini). As the loading progressed, it got slower and slower. I tried halting the process, creating a checkpoint and resuming it again. But it did not seem to help (even restarting the virtuoso instance did not). The remaining few million triples are taking forever to load.
Did I miss any performance tuning that can improve the process? Or is this the normal behaviour?
