neomodel-locust

Performance tests for neomodel

How to use

It's based on locust, so in order to run it, run the following commands :

# Start the test API
# Note that it's tied to a branch for the neomodel repo
pipenv install
pipenv run start

# In a separate terminal
pipenv run locust

Then, go to the Locust UI, and pass the following parameters (adjust accordingly):

Parameter	Value (default)
Number of users	1
Ramp up	1
Host	http://localhost:8000
Run time (advanced)	10

neomodel overhead vs Neo4j driver

For this test, we compared pushing a Cypher query through :

• Neo4j driver low-level session.run
• neomodel db.cypher_query(which wraps session.run)
• Neo4j driver high-level driver.execute_query

The results show that neomodel adds very little overhead to the Neo4j driver.

Sync vs Async comparison

For this test, we compared sync neomodel vs async neomodel, in two ways :

• Serial queries - Async should not provide a boost here since we wait for each query before going to the next ; but also should not too much overhead
• Concurrent queries - We make use of asyncio.gather for async, and create a thread pool for sync so that queries happen concurrently. Here, async should be more performant than sync
