Hi Michael, there are several warmup things going on, which already have happened if you execute against server.
So I recommend running the query once or twice upfront. Also make sure to create the ExecutionEngine only once, together with the GraphDatabaseService. Also make sure you use a similar configuration (heap and memory mapping for your embedded graph database). I think you might be better off using the unmanaged extension <http://neo4j.com/docs/stable/server-unmanaged-extensions.html> that Stefan sent you, then you can have best of both worlds. One example for Cypher is here in this example repo <https://github.com/neo4j-contrib/developer-resources/blob/gh-pages/language-guides/java/server-extension> : https://github.com/neo4j-contrib/developer-resources/blob/gh-pages/language-guides/java/server-extension/src/main/java/example/extension/movies/MovieResource.java Cheers, Michael On Tue, Nov 25, 2014 at 5:21 PM, <m...@docware.de> wrote: > Hello Michael, > > I have now started with Java embedded tests.
