Hi All,
I am trying to performance tune VOS 7.1.1 which i got from git and i have few
questions about some of the parameters in virtuoso.ini file
First some instruction about my server setup. I have VOS 7.1.1 with 100GB
memory and around 1.4B triples. I have kept following values for buffer:
N
Thanks Kingsley and entire community for this meaning full discussion,
After this discussion, I have 2 follow-up question.
1. How do I create a new empty database in my existing virtuoso and start
loading RDF data into that by default. I think this way I will be using
column-wise structure.
2.
e virtuoso : I recompile it from source
and then used my older ini file as i have made some performance tuning it that.

Hi All,
I am using Virtuoso (Open Source) 7.1.0 and read about support of column-store
structure in virtuoso.

Hi,
I want to update virtuoso (open source) from 7.00.3203 to latest version 7.1.0.
I could not find any update instructions for this version. Included

Is there any documentation to upgrade to v7.1.0 ?

"log_enable(3,1);" mentioned in 2nd link did the trick. I am able to delete

Hi All,
I bulk loaded 11M rdf file (.ttl) into virtuoso graph "A" using "ld_dir" and
"rdf_loader_run" and it took 8.5 hours which seems a lot slower considering
virtuoso can load data at 36K per second on a single 4 core machine as per
virtuoso documentation. ( http://goo.gl/D5zw1)
Considering
send dump of "ps -ef" in previous reply , please see that to confirm if there
is any nsflock daemon. i see "nfsoid" and "locked" process.
thanks for your help
