Performance insertion with and without index

I did a couple of tests.

Based on some great suggestions from Wes, etc., I set up some of the neo4j features without a cache that you need to embed on a large scale in a multi-threaded environment, and the performance is pretty good.

However, when I entered the index (on the nodes), performance was greatly degraded. The difference is 5 times. Are there any configuration settings to make them better?

Thanks in advance,

Sechin

Inserting nodes (or relationships) into the Lucene index is expensive. Lucene is a powerful yet sophisticated tool for finding full-text / keywords. Compared to an open database, it is rather slow.
