Release 2.0	5 283 blocks	30 829 blocks	Slower because transaction are now mandatory with the new neo4j driver
Release 2.1	6 161 blocks	35 416 blocks	Moving to neo4j 3.3.4
Build 447	6 146 blocks	43 109 blocks	Removed constraint on transaction txid / addresses cache / no depth to retrieve block

This is the script used to benchmark blockchain2graph :

#!/bin/bash

# Starting.
echo `date`

# Install the application.
sudo service tomcat8 stop
sudo service neo4j stop
sudo rm blockchain2graph.war
sudo rm -rdf /var/lib/tomcat8/logs/*
sudo rm -rdf /var/lib/tomcat8/webapps/*
sudo rm -rdf /var/lib/neo4j/data/
sudo wget -nv -O blockchain2graph.war https://github.com/straumat/blockchain2graph/releases/download/version-2.0/blockchain2graph.war
sudo jar -uf blockchain2graph.war WEB-INF/classes/application.properties
sudo cp blockchain2graph.war /var/lib/tomcat8/webapps

# Starting and configuring neo4j.
sudo service neo4j start
sleep 60s
curl -H "Content-Type: application/json" -X POST -d '{"password":"b2g135!"}' -u neo4j:neo4j http://localhost:7474/user/neo4j/password

# Starting tomcat.
sudo service tomcat8 start

# First benchmark after one hour.
sleep 1h
echo After one hour
cypher-shell -u neo4j -p b2g135! 'MATCH (n:BitcoinBlock) RETURN count(n);'

# Second benchmark after one day.
sleep 23h 
echo After one day
cypher-shell -u neo4j -p b2g135! 'MATCH (n:BitcoinBlock) RETURN count(n);'

To run it, use this command : chmod +x nohup.out;rm nohup.out ; nohup ./perf.sh &
