问题
When i run a Cypher query in UI, only one core in server is going up and the query gets stuck or responds very slow.
I use Neo4j 3.0.7 Community.
Someone have idea what i can tune for using all cores?

A single Cypher query is limited to a single thread. See this tweet from late 2015 by Stefan Armbruster:
A cypher statement is (in most cases) one transaction and therefore only on one thread.
If your query is slow, you can use various tricks for optimizing it: this blog post is a good starting point.
