Some little tests around ES and java 6/7
Raw
tests.md

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

System metrics :

  • CPU usage :

* Load average

ES/java metrics

  • GC collection time

  • JVM thread count

  • ES indexing time

  • ES merges time
