To determine whether a file's content is already in sync, Puppet computes a checksum of it and of the target content, and compares. By default, it uses MD5 for the checksums, and that's probably what take most of the 2-3 seconds per file. You might be able to speed it up a bit by setting "checksum => md5lite" on your file resources. Or you could probably speed it up a lot, at the cost of a significant risk of false positive comparisons, by setting "checksum => mtime" to use last modification time for the checksum. Really, though, those are band aids. If you have a large number of related files then you probably shouldn't be managing them individually via Puppet at all. Instead, package them up and manage the package, or sync them directly with your version-control repository (under Puppet control, if you wish).
