I'm curious :) the performance issues are about Jena+Mulgara or Jena alone?

What do you mean by "query a set of models, in sequence or in union"?  You

For example I want to find all statements about X, no matter in what model
they are, and subsequently find also the model for each result. For the
moment we're creating our own (lucene) index over all  Jena models
(ignoring  blank nodes) to  do this.
