just something to consider when we'll get to move gerrit from ec2: "The first step to scaling is to scale your master server. Some easy, but pricey ways to scale your master are: Adding cores, some of the larger installations use 24 core machines Adding RAM, most of the larger installations have at least 48GM, some have 100+GB Ensure fast disk IO, SSDs help Network, I suspect that most large installs use 10Gb ethernet "[1] last point doesn't seem relevant. but i was surprised by the first two. I'll take this into consideration when we get to this one. [1] http://code.google.com/p/gerrit/wiki/Scaling
