Hi Sulabh,
what do you mean by 'local' mode?
The batch inserter can only be used in a single threaded environment. You
shouldn't use it in a concurrent env as it will fail unpredictably.
Please use the EmbeddedGraphDatabase instead.

some of the stuff in the war folder. Oh and took out all the

That is rather a case of warming up your caches.
Determining the traversal speed from the first run is not a good benchmark as
it doesn't represent production usage :)
The same (warming up) is true for all kinds of benchmarks (except for startup

Agelos,
sorry, didn't want to sound that way.
512M ram is not very much for larger graphs. Neo4j has to cache nodes,
relationships in the heap as well as you own datastructures.
The memory mapped files for the datastores are kept outside the heap.
Normally with your 4G I'd suggest using
301 - 400 of 600 matches
