Triple Loading "What doesn’t show in the numbers is the fact that the entire load process is CPU bound, it’s not disk accesses that’s taking time. Also, the amount of triples, 473589, isn’t enough to fill up the in-memory cache MySQL maintains (here), not even importing a large dataset like Jim’s 6.7 million scuttered statements (converted into NTriples with jim2ntriples) seems to be. With bulk loading turned on, that entire process takes about 34 minutes, equivalent to about 3300 triples per second, as compared to the about 3000 triples per second for the best case above."
