Which version of MonetDB are you using?
Which OS are you using?
Did you install a pre-built binary version of MonetDB, or are did you compile it yourself from sources (HG or released tarball?)? We are using MonetDB Database Server Toolkit v1.1 (Feb2013-SP3), installed on Ubuntu server 12.04LTS. We are using the packages you kindly provide in your repository.
And, as Martin suggested, would you be able to share your database schema, queries, and possibly even data with us (or at least some more data characteristic)?
I will look at this. I guess the schema can be shared. As for the data, it cannot as it relates the hospital medical data.
Alternatively, could you profile the behavior using Stetoscope (as Martin suggests) or by simply prefixing your SQL queries with TRACE and share the (performance/profiling-) results?
Yep, I will do this. Thanks, Franck
