Logstash + ES + Java 6 & 7
ES VMs : 1 CPU, 2G of RAM, dedicated to ES. ES process got 1G of RAM. Running version 0.20.5 Logstash machine : 1 collector process, input TCP, output to redis and 1 indexer process input redis and output in Y to both ES servers
pre flight test at 10h27, cleaned indices and then started indexing at 10h37. This test is not about performance in itself, but more about ES behaviour when changing the JVM. Ended around 11h15
first is the VM running under java 6, then java 7
