Neo4j jmeter test

[metamoi]

I ran the Apache JMeter of neo4j.
The number of nodes is about 7,300,000, properties are 41,000,000 and
relations are 27,000,000.
I set the jmeter as follows:
the number of threads - 10
Loop count - 10,000

I used the cypher query of php client on my own apache web server to
run JMeter.

I got the following results:

Average: 54
Min: 20
Max: 21024
Std. Dev.: 203.03
Throughput: 179.7/sec

I think that the min value and the average value are quite good for
service,
but standard deviation seems to be too high to run a service.

I would like to hear others' opinion about this result.
Do you think that the result shows that the performance of neo4j is
so problematic to run product service?

When I decreased the loop count, I got the lower std. dev. and max
value.

Depends on what you want to do.

What version do you run?

Did you have a warmup period?

I'm testing the neo4j-enterprise-1.7-SNAPSHOT for common-friend
suggestion.

Metamoi,
I am suspecting GC pauses to be involved there. Any chance you can profile this?

Cheers,

You should try with the new GC resistant cache then. Add:

    cache_type=gcr

in your neo4j config to use ut.

Where exactly does this parameter belong to - neo4j.properties I suppose ?

Thanks,

Andrii

[Michael Hunger]

Today it is cache_type=hpc

yes, in neo4j.properties for neo4j-enterprise

You can also try cache_type=none

can help too.

Hi,

I wanted to know how can we populate data in neo4j DB before starting jmeter test and clear Neo4j DB after test.

Thanks in advance!

[Michael Hunger]

You can populate the db by either running a program that generates the data or use a data generator like graphgen (graphgen.neoxygen.io) or run a Cypher script with the necessary statements e.g. with bin/neo4j-shell -file import.cypher
