Hi, Adding a literal (with average size around ~400 bytes if the numbers are correct) should not result in such a big difference of injection times.
Could you give some more information regarding setup so we can track down the cause of this. Good things to know would be: o java version and jvm switches/configuration (heap size, gc settings etc) o amount of RAM on the machine o neo4j kernel version (1.1-SNAPSHOT or 1.0?) o configuration passed into the neo4j kernel if any o size of the different store files in the neo4j db directory (after injection of data) Regards, Johan On Fri, May 7, 2010 at 10:26 AM, Mattias Persson <matt...@neotechnology.com> wrote: > I'm not sure why it's taking such a long time, it shouldn't be that slow. > I'll see if I can get time to look into that... but I don't know when > exactly.
