Our team has downloaded the latest release of TDB for some preliminary efforts to migrate to triple stores from SMW mysql etc.
We ran into performance issues with MySQL so the options around doing some benchmarks are potentially critical for us. We have been simply doing tdbload operations on various small OWL and RDF sets. We'd been able to query pretty well as we might have expected with tdbquery. We've loaded a large/huge dataset from the Social Intelligence Benchmark (SIB) and while the load seemed to complete, efforts to run tdbquery as well as tdbdump all blow up with Heap limits. We've got 4GB ram allocated on our Ubuntu 9.10 VM system but haven't gotten things to run even after adjusting JVM_ARGS to -Xmx2400m Any more blog references to pursue to get us going ? TIA Bruce R.
