I probably should have mentioned, but this is running on AWS small, which is 2G memory, http://aws.amazon.com/ec2/instance-types/.
Could that be a reason?
Can you guys tell me of your machine specs, please? I probably should use a more beefy instance. 

Also @chrismd, would you mind explaining what some of those graphite
monitoring stats are, please?

commitedPoints - is this how much requests is coming in and waiting to
be written/updated? Seems the same as "metricsReceived"? The two graphs
look pretty identical.

Pretty much, what are "points"? Is it an update request? I assume
updateOperations is the carbon process to update the metricsReceived.

Thanks!
