Comment 8 for bug 1178707

The instances work load range from

 - an nginx proxy server, just proxies connections to different backends running in-memory database
  avg cpu: 30%

- a server running inhouse in-memory database , taking connections from the nginx proxy servers
  avg cpu: 20%

- queue worker servers
  avg cpu: 75%

The nginx proxy servers and memory databases do a large amount of network traffic, usually around 25k pkts/sec on the proxy server, with around 15k pkts/sec on the database servers
