Well, no significant change in facter's runtime give or take a factor of x50. What's two orders of magnitude between friends? Really, a five-second runtime for a fact is pretty extreme, but even that seems not to match the timings you report -- it looks more like your external fact takes 32 seconds to run. In the past, Puppet has sometimes had issues with unnecessarily evaluating facts more than once, so perhaps such an issue is magnifying the effect of your slow fact. Or perhaps the fact value is extremely large. Or maybe evaluating the fact leaves the node in a state that slows or delays communication with the master. It is probably worth your while to run the agent with the "--test --evaltrace" options to get a more detailed breakdown of how the time is being consumed. Please post the whole timing report. Also, it might be helpful to know what your external fact script is actually doing.

The issue is likely to be tied to details of your external fact script, so although there may indeed be a bug to report, I don't think we know yet what it might be.
