Marcin, I used to work with eXist 2.5 years ago. JCR and XML:DB concepts are actually have some common moments. The reason of eXist's performance is, as far as I know, the fact that eXists keeps the whole database as in-memory DOM model and, in addition uses advanced indexes like those that allow quick processing of XPath expressions like "/x//y".

Hi, Recently I've discovered XML database quite similar in general concepts to Jackrabbit, in fact it does not provide versioning and referencing between nodes but it is really fast as I compared it with Jackrabbit, especially in querying and importing nodes, question is why Jackrabbit performs so badly in comparison to eXist?
