Then perhaps you should be looking for a boat?

Puppet''s performance and scaling problems aren''t that unique.
It''s
pretty much the same thing that happened with Rails - people started
using and deploying it without considering the performance
implications, and were surprised when it didn''t scale. Rails *does*
scale, just not out of the box. I''d wager that, to a certain extent,
Puppet is in the same boat.

Performance, expressiveness, stability. Pick two.
