Hi, I've never used CFEngine and don't have input on those benchmarks other than they seem silly. But, fwiw...
- scaling Puppet masters seems to be straighforward and well documented (there are chapters in books on it) - Performance in Puppet 3 is much better. Check out this presentation from PuppetConf - http://www.youtube.com/watch?v=8h2PbdFi0OU - The key bottleneck of a Puppet Master is cpu usage when compiling catalogs. How long catalogs take to compile varies widely depending on your usage. I currently manage over 600 Windows nodes on a single, small, ec2 instance (one core) that has no problem keeping up. Most of the nodes run every 4 hours and we use splay settings to randomize the run intervals. We also currently have very small catalogs for these nodes (unlike our Linux server nodes handled by a separate master) that compile extremely fast. - Puppet ships with a rarely mentioned load testing tool. Google this and try it out. See how it will handle your volume. Eventually how big of a server/cluster you need becomes a simple math problem. - Also, really, how important is paying more for a bigger server to you when considering usability/features/community/momentum/etc differences?
