Neo4J Query response is slow while running multiple queries at once

Hii,

Neo4J query response is very slow when I am running 100s queries at once.
To explain my problem, I have a query that takes milli seconds time for result, If I run it one time, all good. But if I run the same query 100 times all at once, each query is taking minutes for the result. Please suggest a solution.

How are you executing these queries? Can you provide the code?
