....and tweak the memory allocation settings for the jvm and neo... -----Original Message----- From: Peter Neubauer <peter.neuba...@neotechnology.com> Date: Mon, 11 Jan 2010 23:19:07 To: Neo user discussions<user@lists.neo4j.org> Subject: Re: [Neo] Neo is very slow (I think I'm being stupid)
Tim, I think the structure is quite normal, would be good to see the code, you could send it to me off-list. That way I get an impression on both the querying code, the dataset size and maybe test-run it.
