• avoid []byte to string conversions
• re-use buffers or objects (use sync.Pool in Go 1.3)
• pre-allocate slices make([]byte, 0, 1024)

mindscratch: now that some people are here, here's an earlier question: hen performing a rolling update (https://github.com/GoogleCloudPlatform/kubernet...) ...how does kubernetes know which image to update if a pod has multiple containers with different images 2:23 PM

jbeda: mindscratch: Right now, it is run client side and is kind of a little too simple. 2:24 PM It captures the list of pods and just kills them one by one. It assumes there is a replication controller that will 'heal' them with the new version 2:24 PM

jbeda: Ideally, the 'upgrader' would make sure that the new pods come up okay, do some health checking, etc.

Or, they can be used as a traditional controller, initializing and controllers and hooking them up to models. Mostly, controller's are a really great way of organizing your application's code.

Controllers provide a number of handy features such as:
