Hi Adam, the server specs you posted are not so important. What disks did you use? They should be SSD or 15k RPM SAS to make it faster. Virtuoso can parse multi thread if you split the files before loading, but hdd speed is still the bottleneck. Sebastian On June 20, 2019 2:37:16 PM

Is that with SSD harddisks? Isn't the bottleneck the io traffic to the harddisks? (I suppose your are not loading into RAM?) What was you hardware configuration? best regards Finn http://people.compute.dtu.dk/faan/ On 20/06/2019 14:37, Adam Sanchez wrote: For your information a) It took

For your information a) It took 10.2 days to load the Wikidata RDF dump (wikidata-20190513-all-BETA.ttl, 379G) in Blazegraph 2.1.5. The bigdata.jnl file turned to be 1.3T Server technical features Architecture: x86_64 CPU op-mode(s):32-bit, 64-bit Byte Order:Little

V4 has 8 cores instead of 6. But well, it's a server grade config on purpose! Vito Il giorno mar 4 giu 2019 alle ore 16:32 Guillaume Lederrey < gleder...@wikimedia.org> ha scritto: > On Tue, Jun 4, 2019 at 3:14 PM Vi to wrote: > > > > AFAIR it's a double Xeon E5-2620 v3. > > With modern CPUs

AFAIR it's a double Xeon E5-2620 v3. With modern CPUs frequency is not so significant. Vito Il giorno mar 4 giu 2019 alle ore 13:00 Adam Sanchez ha scritto: > Thanks Guillaume! > One question more, what is the CPU frequency (GHz)? > > Le mar. 4 juin 2019 à 12:25, Guillaume Lederrey > a écrit

thanks Guillaume. How does that compare to the wikidata footprint of the wikidata service (SQL) not WDQS. I presume it sits in a MyISAM storage container? On Tue, Jun 4, 2019 at 11:25 AM Guillaume Lederrey wrote: > On Tue, Jun 4, 2019 at 12:18 PM Adam Sanchez > wrote: > > > > Hello, > > > >
