Thanks a lot, after some investigation, here are a few results: - the problem was that I had no .opt file and that the default behavior was fixed.opt (or so it seems), when adding a none.opt (or a stats.opt) the performance went from 1200 to 250ms (with the version with the big filter version) - the version with VALUES went down to 150ms using none.opt or stats.opt, that's really cool - the version with a big filter went down to 150ms when I turn off optimizations (the big union takes more time than a simple filter)
I'll open the following JIRA issues: * documenting that fixed.opt is the default when there is no file * documenting that --tdb should be preferred over --loc in most cases in tdbquery * feature request: ability to turn off some (or all) optimizations for a query, a bit like https://wiki.blazegraph.com/wiki/index.php/QueryHints I'm satisfied with the current state. Best, -- Elie
